42-year-old Fathima Benazir, a molecular biologist has come up with a new non-toxic used to test for viruses in labs
The new dye, derived from natural ingredients, can be handled without gloves and could revolutionise the field of DNA testing
Dye prices have skyrocketed after the pandemic and a 500 ul vial is enough for 10,000 RT-PCR tests
A new discovery could revolutionise DNA testing, which has become so important after the onset of the Covid-19 pandemic. Even more remarkably, that breakthrough was made in a kitchen by a researcher whose love of science prompted her to tread the unbeaten path.
With the eruption of Covid-19, the number of RT-PCR tests, regarded as the “gold” standard of testing) have skyrocketed. But with the increased demand for such tests there are also increased lab and environment hazards. This is because the fluorescent (or fluorophore) dyes used in the testing of nucleic acids such as DNA and RNA, are often heavily toxic to lab staff and pose a serious problem when it comes to disposal.
A new non-toxic fluorescent dye invented by a Bengaluru-based scientist could potentially revolutionise how this testing is done in the near future.
Fathima Benazir, 42, a molecular biologist by training, always knew that she wanted to be a scientist, but that it was ultimately a failure to get into an MBBS programme (by a 2% margin), which pushed her towards biotechnology.
This is the third part of the series called “Scientist Says” where we bring for our readers the significant research works of young scientists.
Rashida Bakait from India Tomorrow interviews Dr. Mohammed Rameez who is presently working as Academia Sinica postdoctoral research fellow at the Institute of Chemistry, Academia Sinica, Taiwan.
Here are the excerpts of the interview with him.
Q. What is the topic of your research and please give a brief explanation?
Ans: With the increased manufacturing activities, large amount of carbon dioxide (CO2) is being released in the environment, causing Earth–Carbon disparity, leading to global warming issue. Further, there is an additional rising demand of fine chemicals such as p-benzoquinone, which are obtained from the processing of fossil fuels. However, these processes operate under high energy and high pressure conditions generating more CO2. Therefore, decreasing CO2 production and transforming CO2 into valuable solar fuels seem to be an essential issue to be considered for future sustainable development. So, this scenario has given the researchers a challenging topic of as to how to reduce the amount of CO2 and further convert it into useful low-carbon fuels. Hence, my research topic is based on reduction of carbon dioxide to other useful chemicals using electricity and catalysts. This process is known as electroreduction of CO2.
My research is developing an ideal resource-efficient solution based on catalysts i.e. artificial photosynthesis – mimicking how plants use sustainable sources of sunlight, CO2 and water to drive the production of energy-rich carbohydrates. As such, promising research efforts have been intensified in reducing CO2 to similar energy-rich fuels and chemical feedstocks through electro-catalytic routes. Recently, we report a novel g-C3N4/Cu2O-FeOheterogeneous nanocomposite catalyst for CO2 electrochemical reduction to CO, with a maximum Faradaic efficiency of 84.4% at a low onset overpotential. This research was published in topmost journal in the field of environmental engineering. This research was done in Academia Sinica, a premier research institute of Taiwan. A PhD student Girma from Ethiopia and I worked on it in Prof. Hung’s lab. I was also one of the corresponding authors.
Q. What is the motive/ aim of your research?
Ans: Different semiconducting materials and metals, such as Pt, Pd, TiO2, SrTiO3 CdS, g-C3N4, ZnO, Bi2WO6 and so on have been used as catalyst for CO2 reduction. However, the practical applications of these catalysts for CO2 reduction are still limited by the low CO2 conversion efficiency due to low light harvesting efficiency, high production cost, low catalytic activity, insufficient catalyst durability and a lack of mechanistic understanding.
Hence, our aim was integrating heterostructures containing oxides of non-noble metals, such as iron and copper with g-C3N4 that may result in stable materials that could function as active electrochemical catalysts for CO2 reduction.
Q. What important findings/aspects are highlighted in your research?
Ans: We prepared a novel g-C3N4/Cu2O-FeO heterostructure nanocomposite catalyst by a simple hydrothermal synthetic route and tested it for electrochemical CO2 reduction in aqueous systems. To the best of our knowledge, this is the first experimental report on a hybrid g-C3N4/Cu2O-FeO nanocomposite for electrochemical CO2 reduction. We demonstrated that g-C3N4/Cu2O-FeO is a promising electrocatalysts for CO2 reduction in neutral medium. Incorporating mixed metal oxide into g-C3N4 layers could be a potential strategy to improve the electrocatalytic catalytic activity of the composite materials. With careful experimental design, this research may help us obtain a library of highly efficient water stable and less toxic catalysts optimal for various catalytic applications.
Q. What kind of challenges did you face?
Ans: Many semiconductors, doped and sensitized semiconductors have been used as photocatalysts for CO2 reduction for higher conversion efficiency. The selectivity of products not only depends on the catalysts’ compositions but also on the choice of reductant and the solvent. However, the practical applications of these catalyst for CO2 reduction are still limited by the low CO2 conversion efficiency. It is important to raise the photocatalytic conversion efficiency and long-term stability to make this process economically feasible. Here, our main challenge was to enhance the selectivity and efficiency of the process for the novel g-C3N4/Cu2O-FeO catalyst, which uses earth abundant materials.
Q. Any scholarships or awards for this research?
Ans: We got financial support from Ministry of Science and Technology of Taiwan (109-2113-M-001-020) and Academia Sinica (AS-KPQ-106-DDPP) for this research on CO2 reduction.
I have received Taiwan government’s most prestigious scholarship for PhD ‘TIGP’ and was given an opportunity to study and carry out my research in the Academia Sinica and National Chiao Tung University, a renowned research institution of Taiwan and one of the top three Universities. It was a type of dual degree with my research focused on Sustainable Chemical Science and Technology. After obtaining PhD, I also got Song Pei Wu applied chemistry thesis award for my thesis on Perovskite solar cells. Moreover, two of my research papers also received the best paper award from my university ‘National Chiao Tung University’.
Currently, I have been awarded the most prestigious postdoctoral fellowship in Taiwan (Academia Sinica postdoctoral research fellow) offered by Academia Sinica and I am working as a Postdoctoral research scholar here.
Q. How do you think your research would be beneficial to the society or industry?
Ans. I hope that this research would help in solving the prevalent issue of global warming befalling due to the rapid industrial developments across the globe. Currently, the conversion efficiency is too low to be practically useful in industry, this research would definitely help solving the existing low conversion efficiency. We are also confident that the proposed hybrid low-dimensional functional materials would help in promoting the conversion of the product yields to some extents and to gain in-depth understanding of the basic principle of CO2 reduction using the advanced spectroscopy/dynamics techniques available in our laboratory. Based on our results we will be able to design better, cheaper and inexpensive catalysts. Finally, we hope these catalysts can be used for a large-scale industrial fixation of carbon dioxide to useful chemicals. This can help us achieve two goals – 1) CO2 amount reduction and 2) valuable chemical productions without using fossil fuel. Ultimately, we will be able to attain the goal of sustainable development.
Q. When did you begin and complete your research?
Ans: I joined the above mentioned project in the month of June 2020, after finishing my PhD, and the first draft of the manuscript was ready by the end of November 2020. The research was finally published in the reputed journal named Applied Catalysis B: Environmental inthe field of environmental engineering in the month of March 2021.
Q. Any new research you are working on now?
Ans: The recent research still requires solutions like finding a viable approach, providing better stability, reducing toxicity and superior catalytic performance. Currently we are working on introducing newer class of materials known as Perovskite. Our goal in this proposal is to develop novel photocatalysts that are inexpensive and efficient. Additionally, the photocatalytic materials should be able to generate large number of electron-hole pairs, while separating charges efficiently at the same time, and providing large amount of active catalytic sites at the interface between the surface of the photocatalyst and the CO2 carriers (either in liquid phase or in gas phase).
Q. What was the conclusion of your research?
Ans. We successfully demonstrated that cheaper catalyst can also work efficiently as expensive catalysts for CO2 reduction with better efficiency and selectivity. More details can be found in our research article.
Q. How do you think your research can be carried forward?
Ans. We expect to establish a standard protocol for employing catalysts for efficient Electro Chemical systems which may ultimately lead to development of the large-scale integrated reactor, including highly efficient buffered system, high conductivity membrane material, and large surface area electrode (e.g. gas diffusion electrode, single-atom membrane, and bio-conductive membrane electrodes). Further, we will be able to tune the selectivity of products by tuning the solvents. Ultimately, research groups around the world will be able to harness CO2 for various applications.
Q. Lastly, please give some tips to the budding scientists?
Ans. My advice to the budding scientists is that they should keep themselves updated with the recent literature and findings. Never lose hope as it takes time to obtain results. Always have plan B and C ready for the research and experiments.

This is the sixth part of the series – `Scientist Says’ – where we bring for our readers the significant and commendable research works of young scientists in various fields.
Dr. Imtiyaz Ahmad Bhat started working as a researcher in the year 2013 with Prof. P.S Mukherjee lab, Inorganic and Physical Chemistry department, IISc Bangalore. He completed his Ph.D in 2018 and worked as a Research Associate in the same department. Currently, Dr. Imtiyaz is working as a post-doctoral fellow in King Abdullah University of Science and Technology (KAUST), Saudi Arabia. He shares his significant research works withRashida Bakait of India Tomorrow. Here are the excerpts of the interview.
Q. To begin with, please explain in brief to our readers about `Supramolecular Chemistry’ and the research works associated with the subject.
Ans. Nature has inspired scientists to exploit the potency of weak non-covalent interactions to form complex functional Supramolecules, with wide range of applications, which led to the birth of a new field of chemistry called ‘Supramolecular chemistry’ i.e. chemistry ‘beyond molecule’. Supramolecules are large complex molecules formed upon aggregation of smaller constituent building blocks through non-covalent interactions by a process called ‘self-assembly’. ‘Self-assembly’ is a spontaneous process where components, either separated or linked, reversibly form complex ordered aggregates without any external direction. Supramolecular chemistry has emerged as a broad field and has given rise to vast number of diverse structures by using a variety of non-covalent intermolecular interactions.
Over the past two decades, various methodologies of co-ordination driven self-assembly for the rational design of polygons and 3D supramolecular including tetrahedra, cubes, octahedra, cuboctahedra, and others have been developed. Enzymes, which are nature’s molecular containers, possess molecular pockets capable of binding substrates through non-covalent interactions and catalyze many important enzymatic reactions. Over the last two decades, with the advent of co-ordination driven self-assembly, the focus has greatly shifted to exploiting weak metal–ligand coordination for the self-assembly of molecular containers from individual components. The simple yet dynamic nature of coordination driven self-assembly has led to the construction of various capsules and cages with nanometre-size cavities capable of various applications. The shape and size of inner cavity of the coordination cages, even those not possessing definite covalent interactions between the catalyst and substrate, play a paramount role in altering the reactivity and properties of the contained molecules.
The central theme of my doctoral research interest in IISc has been in the area of co-ordination driven supramolecular chemistry, arguably one of the hottest areas of chemical sciences. In my research work at IISc Bangalore, I was specifically engaged in developing novel coordination cages possessing confined cavity and demonstrate their applications in cavity directed catalysis and stimuli-responsive targeted drug delivery.
Besides this, my current research focus at King Abdullah University of Science and technology, Saudi Arabia as Post-doctoral fellow is to design and synthesize the Imine-based macrocycle which will act as Non Adaptive Crystal Systems (NACs) and will eventually be used for separation of hydrocarbon and their derivatives. These Imine based macrocycles offer plenty of merits, such as easy preparation, low cost, high recyclability, chemical resistance, and thermal stability and hence makes them ideal material for industrial application.
Q. What was the objective of your research?
Ans. The supramolecular coordination complexes are obtained by mixing soluble metals as acceptors and ligand precursors as donors which spontaneously form metal-ligand bonds to generate a single thermodynamically-favoured product. Over the past two decades, various methodologies of coordination driven self-assembly for the rational design of polygons and 3D supramolecules including tetrahedra, cubes, octahedra, cuboctahedra, and others have been developed. My aim was to examine the self-assembly of pyridine and pyrimidine based ligands with square planar Pd(II) and Pt(II) metal ions to get the water soluble supramolecular structures with intrinsic hydrophobic cavity. These supramolecules with intrinsic hydrophobic cavity have a potential to function like the naturally found catalysts i.e enzymes by mimicking the cavity driven enzymatic reactions.
Q. When did you begin and complete your research?
Ans. I started in 2013 as a PhD student in Prof. P. S. Mukherjee lab at IISc Bangalore. Currently. I am working as a post-doctoral fellow in King Abdullah University of Science and Technology (KAUST), Saudi Arabia.
Q. What were the new findings of your research?
Ans. I could successfully synthesize and characterize various water soluble supramolecular structures with different shapes like sphere in sphere, tubes, tetrahedron, molecular barrels etc. and sizes. The tetrahedral cage with confined space was used as supramolecular catalyst to promote the Michael Addition Reaction of Indole and various nitro-styrene derivatives in water. The hydrophobic cavity of water soluble barrel like structures was successfully utilized to encapsulate curcumin and increased its solubility, enhanced its stability against UV light and thus acted as a safe aqueous carrier of curcumin to HeLa cancer cells. Also, an unusual supramolecule with triangular orthobicupola geometry was obtained, which is the first example of its type reported so far. The confined pocket of this cage with unique structural topology has been successfully used for the catalytic intramolecular cycloaddition reaction of substrates containing less reactive alkyne dienophile.
Q. What was the conclusion of your research?
Ans. In conclusion, we could successfully synthesize and characterize a giant double layered spherical structure with 24 Pd (Palladium) ions and 24 Pyrimidine based ligands. The strategy used here for the synthesis of double-shell superstructure establishes new guidelines for the creation of novel complex architectures. To further explore Pyrimidine as donors, various ligands with Pyrimidine as donors were synthesized and their self-assembly with cis-blocked Pt acceptor has led to formation of tube and tetrahedral cage structures. The tetrahedral cage with confined space was used as supramolecular catalyst to promote the Michael addition reaction of indole and various nitro-styrene derivatives. We were able to synthesize and characterize a water soluble barrel and cylindrical assemblies.The hydrophobic cavity of water soluble barrel was successfully utilized to encapsulate curcumin and increased its solubility, enhanced its stability against UV light and thus acted as a safe aqueous carrier of curcumin to HeLa cancer cells. The cylindrical assembly obtained was found to adopt an unusual triangular Orthobicupola geometry, which is the first example of its type reported so far. The confined pocket of this cage with unique structural topology has been successfully used for the catalytic intramolecular cycloaddition reaction of substrates containing less reactive alkyne dienophile.
Q. What kind of challenges did you face?
Ans. Challenges and difficulties are the inherent part of the research and researchers have to find ways to overcome them and materialize their tasks. It was really a herculean task in characterizing these supramolecular structures. However, patience and positive attitude helped me to keep trying and I could finally characterize them well and obtained their crystal structures. As a beginner, I struggled with writing my results and presenting them in scientific journals.
Q. Any scholarships or awards for research?
Ans. My Research Associateship was extended for one more year in IISc for completing research within five years. In 2019 I received Irish research post-doctoral fellowship in Trinity College, Dublin
Q. How do you think your research would be beneficial to the society or industry?
Ans. The 3D metallo-supramolecular architectures with confined cavity have been exploited for many applications such as- guest encapsulation, catalysis and drug delivery etc. we were able to show that organic chemical reactions can be performed in water using these water soluble supramolecular structures. Barrel shaped molecules are highly promising which possess large open windows along with large confined cavity. Our approach provides one of the elegant and efficient methods to design such barrel shaped architectures and their use to perform the catalytic organic transformation in aqueous medium. A lot of effort is going on in the scientific field to design new such systems and utilize them for various applications. The importance of this field could be easily reflected from the 2016 Nobel Prize which was awarded for novel findings in supramolecular chemistry.
Q. How do you think your research can be carried forward?
Ans. The features of coordination driven self-assembly like high directionality, intermediate bond enthalpy and vast diversity of organic ligands make it unique over the other non-covalent self-assembly approaches. The coordination-driven self-assembly was initiated by Lehn and Sauvage and pioneered the field with the introduction of various architectures ranging from ladders, helicases, rings, knots, rotaxanes, catenanes, and several other architectures. Later on, other scientists have taken the field to newer heights by developing novel methodologies and approaches to design and synthesize various discrete metal-organic architectures of distinct shapes, sizes and functionalities. The breadth of coordination driven self-assembly has continuously increased with the introduction of numerous functional supramolecules each year and it keeps on growing with every passing day.
Q. Any new research you are working on now?
Ans. My current research focus at King Abdullah university of Science and technology, Saudi Arabia as Post-doctoral fellow is to design and synthesize the Imine based macrocycle which will act as Non Adaptive Crystal Systems (NACs) and will eventually be used for separation of hydrocarbon and their derivatives. These Imine based macrocycles offer plenty of merits, such as easy preparation, low cost, high recyclability, chemical resistance, and thermal stability and hence makes them ideal material for industrial application.
Q. Give few suggestions to budding scientists.
Ans. For those who have decided to take research as their career, I would like to suggest them that patience is the key and keep learning from the mistakes as this is how it works in research. As a researcher, update yourself with the current literature related to your field that will help you to give new directions to your ongoing projects. Time management is crucial. Plan your experiments in advance so that you are confident about tasks you will be performing. Wishing goodluck to all budding scientists.

This is the fifth part of the series called `Scientist Says’ where we bring for our readers the significant and commendable research works of young scientists.
Dr. Ahamed Irshad is a research associate in the department of chemistry, University of Southern California, Los Angeles. He has been associated with National Science Foundation, US Army, and Department of Energy on various battery projects. He has authored several articles in international journals published by American Chemical Society, Royal Society of Chemistry and Electrochemical Society. He served as the topic editor for Journal of Energy and Power Technology, and reviewer for international journals. He is also a recipient of Cottrell scholar award, Bristol-Myers-Squibb fellowship, Dr. J. C. Gosh medal, and Indian Academy of Science award. He shares some of his significant research works with Rashida BakaitofIndia Tomorrow.
Q. Please briefly explain your research.
Ans: My research interest is on developing novel materials for electrochemical energy conversion and storage devices. The research area can be broadly classified into two: (i) hydrogen fuel production from water and (ii) high energy batteries for electric vehicles.
The first project on hydrogen fuel was carried out during my PhD at Indian Institute of Science, Bangalore. Hydrogen is considered as a fuel for the future. While burning petrol or diesel release huge amount of greenhouse gases, the only by-product of hydrogen fuel is water. Currently, hydrogen is produced from methane by steam-methane reforming. This method also produces CO2 and hence cannot be counted as a green method. My research topic was on utilizing carbon free, inexpensive, and abundant water (H2O) molecules as the hydrogen source and use electricity to split water. The process requires energy close to 237 kJ mol-1 or theoretical voltage of 1.23 V. However, practical voltage is as high as 1.8-2 V due to sluggish kinetics. This limits the efficiency to 65-70 % and necessitates expensive catalysts such as IrO2 or RuO2. My research goal was to design and develop highly active, low-cost, and stable cobalt and nickel-based catalysts to improve the efficiency. The use of inexpensive catalysts would also reduce the overall cost and make hydrogen an attractive fuel.
The battery research was done in collaboration with US Army and Department of Energy at University of Southern California, Los Angeles. There is a growing demand for high energy batteries for electric vehicles. Current lithium-ion battery (LIB) technology has limited range (200-300 miles) and high cost of $130/kWh. In addition, LIBs use toxic cobalt-based materials. In recent years, lithium sulfur (Li-S) batteries have emerged as a promising substitute to LIBs due to its five times high energy density. In addition, sulfur is earth abundant and less expensive. Commercialization of Li-S batteries is still hindered by its inability to charge/discharge quickly for several cycles. This has been attributed to high internal resistance and dissolution of soluble polysulfides. We proposed an electrode design with different carbons to reduce the resistance and developed an interlayer to improve the cyclability.
Q. What was the objective of your research?
Ans: Although water electrolysis is used to produce high purity hydrogen, its widespread deployment is impeded by the high cost. My goal was to develop cost-effective and robust catalysts based on nickel and cobalt instead of expensive platinum (Pt), ruthenium (Ru), and iridium (Ir) . I also wanted to investigate the key factors that affect the stability and activity. Similarly, Li-S battery technology has a high potential to replace LIBs(Lithium batteries). My primary objective was to identify the fundamental origin of the high internal resistance in Li-S batteries using a technique called electrochemical impedance spectroscopy. It was also intended to develop an advanced electrode structure to reduce the resistance that would allow to charge and discharge battery fast. Then again, we proposed a novel interlayer to stop soluble polysulfides diffusing from cathode to anode.
Q. What were the new findings of your research?
Ans: We prepared a series of novel materials such as cobalt-phosphate, cobalt-acetate, manganese-phosphate, etc. for water electrolysis. Our electrochemical quartz crystal microbalance studies suggested that the cobalt-phosphate catalysts are not stable at high voltage. In addition, the catalyst deposition was slow due to poor solubility of Co2+ in phosphate. We proposed the catalyst preparation from an acetate solution because the solubility of Co2+ in acetate is high and a large quantity of materials can be prepared in a short time. Cobalt-acetate also exhibited higher activity than cobalt-phosphate. In the case of Li-S battery, we used electrochemical impedance spectroscopy to probe the internal resistance. Our studies indicated that the high resistance originate from poor interparticle contact and sluggish battery reaction kinetics. When we added high surface area carbon, battery performed much better than before due to improved interparticle contact and high number of reaction sites. Adding an interlayer between electrodes stopped diffusion of soluble polysulfides. As a result of advanced cathode design and additional layer, our Li-S battery could be charged and discharged quickly for several cycles.
Q. What kind of challenges did you face?
Ans: The ideal catalyst should have high activity, stability, and preferably made of earth abundant, inexpensive, and non-toxic materials. It was a great challenge to incorporate all the features in a single material. For instance, cobalt-phosphate was very active but not stable. Low-cost manganese-phosphate didn’t show any catalytic activity or stability whereas highly expensive iridium-phosphate exhibited highest activity. Among all the materials tested, we identified cobalt-acetate as the most promising catalyst that showed high activity, stability, and relatively low cost. In the case of Li-S (Lithium-Sulfur) battery testing, identifying the key factors affecting the battery performance was a bit challenging. Impedance spectroscopy aided us to isolate a few factors that affected battery performance significantly. Fabrication of electrodes with different compositions and optimizing the electrode design was a herculean task.
Q. Any scholarship or award for research.
Ans: The battery project was financially supported by various federal and private agencies such as National Science Foundation, US Army, Department of Energy, and a battery startup called STAQ Energy. I was awarded the prestigious Cottrell award by the US National Science Foundation (NSF) and Research Corporation in 2020. I am also a recipient of Dr. J. C. Gosh gold medal in Physical Chemistry and Bristol-Myers-Squibb fellowship. The Council of Scientific and Industrial Research (CSIR), India, provided me fellowship for five years during my PhD. I also received Indian Academy of Science fellowship.
Q. How do you think your research would be beneficial to the society or industry?
Ans: There is a gradual increase in the CO2 and other greenhouse gases in the atmosphere. The transport sector contributes almost 30 % of the greenhouse gases. Moreover, the petrol and diesel price keep increasing every day, and these fuels will run out soon. It is the time to look for clean fuel like hydrogen. My research findings on low-cost catalysts will reduce the hydrogen fuel price and improve the efficiency of electrolyzer. It is also possible to interface the electrolyzer with solar panel or wind turbine to store renewable energy. Similarly, high energy batteries are essential for electric vehicles and portable applications. Our results on Li-S batteries will advance the battery technology beyond lithium-ion battery and reduce the weight and cost of car batteries. The use of high energy batteries will increase the driving range as well. These batteries will be useful for drones and other aerial vehicles also.
Q. When did you begin and complete your research?
Ans: I have been doing battery research since I joined USC in 2017. My PhD started in 2011 and I submitted thesis in 2016. During five years of PhD, I entirely focused on developing catalyst for hydrogen production.
Q. Any other new research you are working on now?
Ans: Currently, I am investigating materials for fluoride-ion battery. In this case, the negatively charged fluoride ions are the charge carriers instead of positively charged lithium ions in lithium-ion battery. This is a new concept that has not been well explored. Another project is on alkaline batteries that are suitable for large scale stationary energy storage. I also continue to work on Li-S batteries for electric vehicles.
Q. How do you think your research can be carried forward further?
Ans: We have an extensive collaboration with scientists and research groups across the world. Currently, we are trying to utilize the technology and skills from different groups to understand the detailed molecular and crystal structure of the catalyst. This would allow us to establish structure-property relationship in these catalysts and investigate the fundamental reaction mechanism. We also communicated with battery companies and federal agencies to examine the feasibility of commercialization of our battery technology.
Q. Tips and suggestions for the budding scientists.
Ans: Career as a scientist is challenging yet a very rewarding experience. To be successful, you need to nurture scientific curiosity, creativity, deep passion, and perseverance. Always make sure that you learn the basic concepts thoroughly and keep yourself updated with scientific literature. Use the early years’ research career to learn as many techniques as possible that will help to tackle many scientific problems in future. Don’t hesitate to expose yourself to different ways of thinking by discussing ideas with peers, gaining experience in different research groups, and creating a network of friends. Communication is also important. You should learn to give presentations and write papers to share your research outputs with others. Just like in any other career, life as a scientist will have many ups and downs, but it’s your choice to scream or enjoy the journey.

Khushboo Mirza was part of the dedicated teams of Chandrayaan 1 and Chandrayaan 2 missions.
Khushboo has reached such heights that schools and colleges in Uttar Pradesh invite her to give talks. Photos: By special arrangement
Chaugori Mohalla is a small Muslim neighbourhood in Uttar Pradesh’s Amroha town, about 200 km from Delhi. To reach the place, one needs to get off NH-24 from Itarsi, about 40 km before Moradabad, and a bumpy 10-km drive on a rough and dusty road would lead to the destination.
The narrow lane has old concrete houses with Urdu nameplates. Men wearing skull caps and women clad in burqas still give the locality a traditional look. Amroha, which is inhabited by both Hindus and Muslims, is called Aman Ki Nagri (town of peace). It has never witnessed a communal riot.
Hailing from this nondescript peaceful town is a young woman, Khushboo Mirza who is locally known as the woman who went to moon. Not for nothing, she has now reached the position of a director-level grade of Scientist F at the Indian Space Research Organisation (ISRO) and was part of the teams of Chandrayaan 1 and Chandrayaan 2 missions.
Khushboo is thrilled over her recent promotion which means she is just two levels below that of the position held by Abdul Kalam and the incumbent ISRO chairperson, Dr K Sivan.
But her life was not without troubles. Born on July 24, 1985, Khushboo lost her father Sikandar Mirza when she was just seven years old. In an unusual move, her mother Farhat broke religious norms to run her husband’s petrol pump to send her children to school. Khushboo studied in a Hindi-medium school till Class 10. She applied for B.Tech at Aligarh Muslim University (AMU) and bagged the seat under the sports quota as she was a volleyball player.
Khushboo at work at an ISRO lab
When Khushboo graduated in 2006, she was offered a software engineer job by American multinational company Adobe. But she applied to ISRO as she wanted to serve “Indian Science”. After joining the space agency, she was first drafted into the dedicated team for the Chandrayaan 1 mission in 2008. Khushboo received the ISRO Team Excellence Award in April 2015. She was also a part of the Chandrayaan 2 mission in 2019.
Even when she was accomplishing achievements in the space, her mother had to face criticism from some of the villagers. But Farhat ignored them and travelled with her daughter to ISRO training programmes across the country.
Khushboo then sought Farhat’s permission to shed the burqa and wear jeans to work. “She wanted to wear jeans, and I allowed her,” Farhat said. “In the absence of her father, and given the fact that she had to travel miles, many people said a lot of unkind things. But I told my daughter to work hard,” added Farhat.
Khushboo maintained the orthodoxy and tradition, and followed religious norms, but they had no impact on her work.
“I do follow our religion and do Namaz five times a day, besides observing fast during the fasting period. But I also wear western clothes. We belong to a progressive family, where modernity can exist along with tradition,” said Khushboo, who once celebrated Eid with her colleagues in an ISRO lab.
She has reached such heights that schools and colleges in Uttar Pradesh invite her to give talks. She keeps telling children, particularly girls, to concentrate on education which alone can provide them with a good future. She has also impressed many Muslim girls to consider education seriously. Khushboo feels that the necessary facilities for primary and high school education in the villages must be stepped up.
Khushboo with her mother Farhat Mirza
Many people in Uttar Pradesh think that she had made a journey to the moon and congratulate her and this why she is called the Moon Girl. Khushboo has emerged as a Muslim icon and a woman icon in Uttar Pradesh. Neither Khushboo nor her family members stereotype women, especially Muslim women. They believe that anyone in the country can fare well if they are provided with a good education.
With education and hard work, success is bound to come. There is no need to bring in religion or orthodoxy here, she said. “Times have changed and the attitude of people towards Muslim girls also needs to change. Our families do educate us.”
The success story of Khushboo Mirza is expected to inspire girls across the country and persuade families to educate their children, raising hopes of a better future not just for these families but the whole country.
