R&D S&E, Systems Research and Analysis


Dr. Kiran Lakkaraju is a Principal Member of the Technical Staff at Sandia National Laboratories, California in the Systems Research & Analysis III group.

Kiran’s research has been marked by extensive interdisciplinary efforts that bring together the social and computational sciences. Currently, he is investigating how wargaming techniques can be used to systematically and quantitatively study national security relevant topics, such as cyber deterrence, conflict escalation, and consensus building.


Kiran has a background in artificial intelligence, multi-agent systems and computational social science. He holds a M.S. and Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign.


Finalist for the Barchi Prize for paper “Experimental wargaming with SIGNAL” (2021).
