Vatsal Jhalani

Vatsal Jhalani received his PhD from California Institute of Technology working with advisor Marco Bernardi, where his research focused on the application and development of ab initio computational methods to study light emission, carrier transport, and ultrafast dynamics in solid-state lighting materials. He is currently a Postdoctoral Scholar with advisor Paul von Allmen focusing on computational modeling of composite thermoelectric materials for next-generation RTGs.
