Tripura-born scientist Sabyasachi Sen earns PhD from Cornell University after contributing to a breakthrough discovery on drought-resilient crops. The research identifies a new plant mechanism regulating water loss, offering hope for climate-resilient agriculture and improved crop productivity amid global water scarcity challenges.
A young researcher from Tripura has brought international recognition to India after being awarded a Doctor of Philosophy degree by Cornell University for his contribution to a major scientific breakthrough related to drought-resilient crops.
Sabyasachi Sen, originally from Agartala, received the prestigious PhD degree from the Robert Frederick Smith School of Chemical and Biomolecular Engineering during the Class of 2026 graduation ceremony held on May 22 in New York.
The achievement has drawn attention within the scientific community because the research may help address one of the world’s most pressing agricultural challenges — maintaining crop productivity during drought conditions and rising global temperatures.
The study, jointly led by Indian-born scientists Sabyasachi Sen and Piyush Jain, was published in the internationally acclaimed journal Proceedings of the National Academy of Sciences. Their findings revealed that plants possess an additional internal mechanism, beyond stomata, to regulate water loss while continuing growth and photosynthesis efficiently.
Scientists involved in the project believe this newly identified mechanism could become a crucial tool for developing future crops capable of using water more efficiently without reducing agricultural productivity. Experts say the discovery arrives at a critical time as several countries continue facing climate-related droughts, water shortages, and food security concerns.
Speaking about the findings, Sen explained that the team identified “a new trait that selectively blocks excess water loss from leaves to the atmosphere without compromising carbon assimilation.” Researchers say this process may eventually support breeders and agricultural scientists in designing stronger and more climate-resilient crop varieties.
Sen’s academic journey began in Tripura, where he studied at Maya Aunty’s Montessori School in Agartala before later completing his schooling at La Martiniere Calcutta. He then pursued a Bachelor of Technology degree in Mechanical Engineering from Indian Institute of Technology Kharagpur, one of India’s premier engineering institutions.
His accomplishment has become a proud moment for Tripura and the broader Indian scientific community. Educationists and researchers have described the achievement as an inspiring example of how students from smaller northeastern states are increasingly making significant contributions to global science and innovation.
