I am a PhD candidate in the Department of Mechanical Engineering at the University of Illinois Urbana-Champaign. My advisor is Dr. Girish Krishnan in the Monolithic Systems Lab. I am a member of the Artificial Intelligence for Future Agricultural Resilience, Management, and Sustainability Institute (AIFARMS) at UIUC. I also collaborate with researchers at Iowa State University as part of COntext-Aware LEarning for Sustainable CybEr-agricultural (COALESCE) program.
Research interest
I work in robotics and autonomy. I am currently interested in object manipulation and grasping. My focus is on grasp stability and slip detection in agricultural work. I am also working on model based control of hybrid rigid-soft manipulators. My previous work has included pre-touch sensing in occluded, cluttered environments.
