Definition
Viviana Gradinaru is a Romanian–American neuroscientist and professor known for her contributions to the development of optogenetic tools and viral vector technologies for mapping and manipulating neural circuits.
Overview
Gradinaru earned her Ph.D. in neuroscience at the University of California, San Diego, under the mentorship of Dr. Karl Deisseroth. She joined the faculty of the California Institute of Technology (Caltech), where she serves as a Professor of Biological Engineering and Neuroscience. Her research focuses on engineering viral vectors for targeted gene delivery, designing genetically encoded sensors and actuators, and applying these tools to study brain function and disease. She has authored numerous peer‑reviewed articles in high‑impact journals and has received several awards, including the NIH Director’s New Innovator Award and the 2021 McKnight Scholar award. Gradinaru is also a co‑founder of several biotech startups that aim to translate optogenetic technologies to clinical applications.
