Pranav Virupaksha

Hi there! I'm a machine learning researcher and engineer interested in computer vision and multimodal AI systems with applications in autonomy and human-computer interaction. Currently, I'm pursuing an M.S. in Computer Science @ Georgia Tech, and working on Social AI with Prof. James M. Rehg.

Previously, I received my B.S. in Computer Science and Linguistics from the University of Illinois Urbana-Champaign and have worked at Anduril Industries and Saab, Inc. on computer vision applications and LLM development, respectively.
