Weizhe Chen

I am a Ph.D. candidate in the Luddy School of Informatics, Computing, and Engineering at Indiana University Bloomington, working with Lantao Liu in Vehicle Autonomy and Intelligence Lab and Roni Khardon in Machine Learning Research Group.

My research aims to empower robots to proactively interact with their environment and people, while effectively addressing uncertainty stemming from various sources. My Ph.D. research focuses on robotic information gathering, which encompasses data-efficient learning and information-driven planning and control.
