About Me

I am a Ph.D. candidate at the Department of Electrical & Computer Engineering, University of Maryland, College Park. Currently, I'm pursuing my Ph.D. as a graduate research assistant at the GAMMA Lab supervised by Prof. Dinesh Manocha. My dissertation research focuses on autonomous robot navigation in complex outdoor environments. Recently, I received the University of Maryland Graduate School's Outstanding Graduate Research Assistant Award for the Academic year 22-23. 

My research interests include,

I have experience in developing autonomous navigation algorithms and porting them to real robot platforms such as  Turtlebot 2, Clearpath Husky, Jackal, Boston Dynamics Spot, and Ghost Vision 60.
