Tushar Krishna is an Assistant Professor in the School of Electrical and Computer Engineering at Georgia Tech, with an Adjunct appointment in the School of Computer Science. He received a Ph.D. in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology in 2014. Prior to that he received a M.S.E in Electrical Engineering from Princeton University in 2009, and a B.Tech in Electrical Engineering from the Indian Institute of Technology (IIT) Delhi in 2007.

Before joining Georgia Tech in 2015, Dr. Krishna worked as a post-doctoral researcher in the VSSAD Group at Intel, Massachusetts and at the Singapore-MIT Alliance for Research and Technology (SMART) Center.

Dr. Krishna's research spans the computing stack: from circuits/physical design to microarchitecture to system software. He has over two dozen publications in leading computer architecture conferences and journals and holds one patent.

Dr. Krishna enjoys creative pursuits, and has dabbled in time-lapse photography, glass flameworking, and building a quadcopter.
