Curriculum Vitae


I received my bachelor’s and master’s degrees in electrical engineering from Indian Institute of Technology Madras in 2009, and the Ph.D. degree in electrical and computer engineering from Colorado State University in 2014 under the supervision of Prof. Edwin K. P. Chong. Before joining SDSMT, I held a postdoctoral position at Arizona State University in the School of Mathematical and Statistical Sciences working with Prof. Hans D. Mittelmann.

My research primarily deals with optimal control, decision making under uncertainty, predictive modeling, data analytics, and optimization in autonomous/semi-autonomous systems.

I am a Senior Member of IEEE.
