For students, the journey may not always be linear, but each step contributes meaningfully to your growth and development .
Jyoti, can you explain your background to our young readers?
I grew up in India, where I developed a deep curiosity about science and the natural world from an early age. I was particularly fascinated by chemistry and space, which gradually shaped my academic interests. I was fortunate to have parents who strongly valued education, and their support helped me stay focused on my studies. Outside the classroom, I enjoyed reading and actively participating in science-related activities. These early experiences played a significant role in guiding me toward a career in science and engineering.
What did you do for graduation/post graduation?
I completed a Bachelor’s (BSc) and Master’s (MSc) degree in Science with a specialization in Organic Chemistry. Subsequently, I pursued a Master of Technology (MTech) in Space Engineering and Rocketry from BITS Mesra. For my doctoral studies at KAIST in South Korea, I focused on the development of eco-friendly gelled bipropellants (bipropellants are a type of rocket propellant consisting of two liquid components: a fuel and an oxidizer) for rocket propulsion, aligning my research with the broader goal of sustainable space technology.
Tell us, why did you choose a career in Sustainable Aviation Technologies?
I have always been deeply interested in space and sustainable technologies. A key turning point came when I discovered the role of chemical energy in powering rockets, which sparked a strong fascination with propulsion systems. I was fortunate to be guided and inspired by dedicated scientists and professors who helped me see how I could contribute to the field of space propulsion through the development of environmentally friendly solutions.
How did you plan the steps to get into the career you wanted?
Following my Master’s degree, I worked on combustion-related projects at IIT Kanpur, which laid a strong foundation for my research interests.
I then pursued a PhD at KAIST, where I focused on green propellants and advanced my expertise in sustainable propulsion technologies.
Following my Master’s degree, I worked as a Senior Project Associate at the Combustion Laboratory, IIT Kanpur, on a Defence Research & Development Organization (DRDO)-funded project focusing on the combustion characteristics of liquid Aviation fuels using advanced diagnostic techniques like chemiluminescence sensors [PMT – Photomultiplier tube]. This hands-on experience was instrumental in developing my understanding of experimental combustion systems, which is often a gap for students in India due to limited access to core engineering lab projects.
Motivated to deepen my expertise in propulsion, I pursued my PhD at KAIST, South Korea, where I was awarded a Full Scholarship to support my PhD research project. Korea was a deliberate choice because of KAIST’s international reputation, world class research facilities, cutting-edge research in propulsion and the opportunity to work on an industrially relevant problem in collaboration with Hanwha Corporation during my PhD. My doctoral research focused on the formulation and rheological characterization of eco-friendly gel bipropellants, aiming to develop safer and sustainable alternatives to conventional rocket fuels. I filed couple of patents from my PhD research findings. Additionally, I was involved in a project on CO₂ management in collaboration with Saudi Aramco & KAIST, which broadened the application scope of my green propulsion research.
After my PhD, I continued as a postdoctoral researcher at KAIST, funded by Khalifa University, where I explored electric control of combustion for clean combustion technology. Subsequently, I was awarded the prestigious Young Korea Research Fellowship (KRF) from Ministry of Science and National research Foundation of South Korea, to further extend my research on hybrid propulsion systems combining green bipropellants and gel technologies. I again filed couple of patents from my Post-Doctoral research.
My postdoctoral research, supported by the Korea Research Fellowship, provided further opportunities for innovation and exploration.
This progression eventually led me to a faculty position at TU Delft, where I continue to engage in academic research and teaching. Along the way, I founded two startups aimed at translating sustainable propulsion technologies into practical applications. The first, SolvGE B.V., was a spinoff dedicated to commercializing my patented hydrogen peroxide concentration technology for zero CO₂ emission solutions, with the goal of bridging laboratory innovations to scalable industrial applications in aerospace propulsion and clean energy sectors. Although SolvGE is currently inactive, I later co-founded J.S.HyE-META Technology to further develop hydrogen peroxide-based systems and machinery designed for energy efficiency and a reduced CO₂ footprint, with applications extending well beyond space propulsion into various industrial domains.
How did you get your first break?
My first significant break came through my MTech project on hypergolic propellants, along with a DRDO-funded research project at IIT Kanpur. These opportunities provided valuable hands-on research experience and helped build my confidence to pursue a PhD. Additionally, securing competitive scholarships enabled me to gain access to world class institutions and further advance my academic and professional journey.
