Nitin Gupta, who achieved All India Rank 1 in the highly competitive IIT-JEE in 2000, embarked on an academic journey that led him from computer science to a pioneering career in neuroscience. After completing his B.Tech in Computer Science from IIT Kanpur in 2004, Gupta's interests shifted dramatically towards biology, a field he now dedicates his research to at the same institution.
During his undergraduate years at IIT Kanpur, Gupta developed a keen interest in biological sciences. This new direction led him to the University of California, San Diego, where he earned a PhD in Bioinformatics and Systems Biology in 2009. His early research bridged the gap between computational methods and biological data, focusing on proteins and genomes.
Following his PhD, Gupta's focus narrowed further into neuroscience. He spent several months at a cognitive neuroscience laboratory at UC San Diego, investigating the neural mechanisms behind decision-making and action. From 2010 to 2014, he served as a postdoctoral researcher at the National Institutes of Health, delving into electrophysiology—the study of electrical activity in neurons.
In 2014, inspired partly by the film 'Swades,' Gupta made the decision to return to India. He joined IIT Kanpur's Department of Biological Sciences and Bioengineering as a faculty member, marking not just a geographical return but also a complete academic transition from his initial computer science background.
Understanding Insect Brains and Behavior
At IIT Kanpur, Nitin Gupta's laboratory is dedicated to understanding how brains process olfactory information and translate it into behavioral responses. His team studies various insects, including grasshoppers, flies, and mosquitoes. They employ a range of advanced techniques, such as electrophysiology, histology, behavioral experiments, genetic manipulation, and computational modeling.
A primary research question for Gupta's lab is how a brain decides what to approach and what to avoid. Mosquitoes serve as a critical model for this research due to their reliance on chemical signals to locate hosts. Human bodies emit a complex array of chemical cues, some attracting mosquitoes and others repelling them.
In a notable 2023 paper published in Nature Communications, Gupta and his collaborators explored how individual odors are represented by neurons within the antennal lobe—a key region of the Aedes aegypti mosquito brain involved in processing smell. Their methods included intracellular electrophysiology, morphological reconstruction, and immunohistochemistry to map neuronal connections. The lab also investigates why neural connections vary between individual insects despite consistent odor responses, and how an insect's internal state, such as a female mosquito's post-blood meal attraction to human odors, modifies its response to smells through neuromodulation.
Broader Impact and Recognition
Beyond insect neuroscience, Gupta's group has also contributed to human mental health. They helped develop TreadWill, an automated cognitive behavioral therapy program designed to improve access to mental health support. A randomized trial in India involving 598 participants demonstrated that those who completed at least half of the program experienced significant reductions in symptoms of depression and and anxiety.
Throughout his career, Nitin Gupta has received numerous accolades. These include the Innovative Young Biotechnologist Award (2015), the Wellcome Trust/DBT India Alliance Fellowship (2016), the Swarnajayanti Fellowship in Life Sciences (2021), the CNR Rao Faculty Award (2022), and the S Ramchandran National Bioscience Award (2023). In 2025, he was appointed to the Joy Gill Chair and received an Excellence-in-Teaching Award from IIT Kanpur, the very institution where his remarkable academic journey began.
