Madhavi, tell us about your background?
I come from Murtizapur, a small town in the Akola district of Maharashtra. My father worked at the State Bank of India, and my mother was a homemaker. Because of my father’s transferable job, I studied in different parts of Maharashtra, which exposed me to diverse experiences. I did my schooling in a Marathi-medium school, where I not only developed a passion for academics but also actively participated in sports such as volleyball, ball badminton, and kho-kho, as well as debates and drama competitions.
Coming from a small town with limited access to technical resources, I was determined to pursue science. After completing higher secondary in the science stream, I consciously chose basic sciences over conventional career paths like engineering or medicine. I went on to complete my BSc and MSc in Physics, which further inspired me to pursue a PhD in the same field.
Reading has always been my hobby. Biographies of great leaders and scientists such as Dr. A.P.J. Abdul Kalam and Swami Vivekananda deeply shaped my vision. Their journeys motivated me to aim for something extraordinary and carve out my own unique path.
What did you study?
I have a PhD (Physics) from, Pune University (2010) with Specialization in Electro-Optical Sensor Development using Nanocomposite
I did my BSc in Physics and MSc (Physics) – Specialization in Solid-State Physics, Amravati University
I also have an MBA (Project Management) from D.Y. Patil University, Pune
I have also authored and published 12 research papers in international journals, further contributing to the field of physics and optical sensor development.
What inspired you to choose a career in Space?
During my PhD, I frequently visited ISRO’s website, and even the ISRO logo became a source of motivation and aspiration for me.
My parents and my Physics professor, Dr. Dongoankar, were my first mentors. Role models like Dr. A.P.J. Abdul Kalam provided constant inspiration—his life and achievements convinced me that with dedication and hard work, one can make a lasting contribution to science and the nation.
How did you shape your career path?
After completing my Master’s degree, I decided to pursue research and registered for a PhD at Pune University. My research focused on the development of nanocomposites for humidity sensors. The problem statement itself was practical and product-oriented, as it aimed to develop relative humidity sensors.
For this work, I adopted both electrical and optical approaches, essentially making it an electro-optical sensor development project. This gave me a unique advantage of working on theory and experiments in parallel, sharpening both my conceptual depth and hands-on skills. Such product-oriented research enriched my academic knowledge and gave me a strong edge during interviews.
Meanwhile, I regularly followed research updates from organizations like DRDO, ISRO, CMET, and CSIR. In 2009, ISRO released an advertisement for a Scientist position. At that time, ISRO was in the global spotlight with Chandrayaan-1 confirming the presence of water on the moon. This fuelled my aspiration to join. I applied, cleared the interview, and in 2010, began my journey as a Scientist at ISRO.
How did you get your first break?
My first break came when I applied for ISRO’s Scientist position. I appeared for the interview based on my Master’s qualifications and was selected in the very first attempt.
What were the challenges you faced, and how did you overcome them?
In today’s competitive era, getting an opportunity to work in one’s desired field is not easy. In India, career opportunities in basic sciences are relatively limited compared to engineering and technology. That made the path more challenging.
Fortunately, my strong academic foundation in Physics and my PhD research gave me confidence. During the ISRO interview, most questions were related to my research, and I was able to answer them with clarity. My preparation and focus turned this challenge into an opportunity.
Where are you working now, and what have been your key contributions?
I am currently working at the Space Applications Centre (SAC), ISRO, Ahmedabad as a Scientist. My work has focused on developing electro-optical payloads (sensors) for Earth observation and interplanetary missions. I have had the privilege of contributing to prestigious missions such as:
* Chandrayaan-3
* Chandrayaan-2
* Mars Orbiter Mission (Mangalyaan)
* Resourcesat-2A
* SPADEX
* Indian Nano-satellite Program
* Airborne missions
My expertise includes optical design, simulations and analysis of optical systems, alignment and optimization of payloads, and electro-optical characterization. Working hours are often long, especially during mission schedules, but the satisfaction of contributing to India’s space program makes every effort worthwhile.
How does your work benefit society?
At ISRO, the work we do is not just a job—it’s a mission. Here, I am deeply involved in the development of electro-optical sensors. These are advanced imaging systems that play a critical role in Earth observation, meteorological applications, and planetary exploration.
The range of applications covered by optical sensors is vast—agriculture, forestry, ocean studies, disaster management, weather forecasting, urban planning, and even the scientific study of planets. The technologies we build directly benefit society by supporting food security, environmental monitoring, and disaster preparedness, while also strengthening India’s technological independence and global standing.
Missions like Chandrayaan and Mangalyaan are not only scientific achievements but also symbols of national pride. Being able to contribute to such endeavours brings immense fulfilment.
Can you share a memorable moment from your career?
The most cherished moment of my career has been serving as “Project Manager for Chandrayaan-3”.
Developing the lander cameras for this mission was a defining experience. These cameras became the “eyes” of the Vikram lander, capturing images of the landing site and confirming the successful touchdown on the lunar South Pole. Watching those 17 minutes of descent, and knowing that my work directly enabled the lander’s success, remains an unforgettable moment of pride—for me, for ISRO, and for the nation.
Your advice to students?
The world of science and technology offers limitless opportunities. If you are curious, passionate, and determined, STEM can turn your dreams into reality.
Do not limit your imagination—space research, innovation, and technology development are fields where your ideas can change lives. Stay curious, keep learning, and take inspiration from global challenges to create impactful solutions.
Remember, every great scientist once began with a dream. With focus and perseverance, you too can make your mark.
What are your future plans?
The space sector is evolving rapidly and holds endless opportunities for innovation and discovery. I aim to continue contributing to ISRO’s missions while deepening my expertise in electro-optical payloads.
On a broader scale, I look forward to mentoring young minds and encouraging them to take up careers in science and space research so that India continues to shine in the global space community.
