Brief Bio
Prof. Aniket Kate is an Associate Professor of Computer Science
at
Purdue University.
He is an applied cryptographer and a privacy researcher.
His research builds on and expands applied cryptography, distributed computing,
and data-driven analysis to solve security/privacy problems in decentralized environments.
His current projects focus on communication privacy and distributed ledgers (or blockchains).
He is a recipient of the 2019 NSF CAREER Award.
Before joining Purdue in 2015, he was a junior faculty member at Saarland University, Germany.
He completed his postdoctoral fellowship at Max Planck Institute for Software Systems (MPI-SWS), Germany. He has received his PhD from the University of Waterloo, Canada, and his masters from IIT-Bombay, India.
