Sean Hardesty Lewis
I am an M.S. student in Information Science at Cornell Tech, where I am fortunate to be advised by Dr. Wendy Ju and Dr. Anthony Townsend.
I work on embodied AI and world models for agents in 3D environments. My research explores how AI systems can perceive, reconstruct, search, simulate, and act across sensor-rich and simulated settings, including cities, built environments, digital environments, and multi-agent systems.
Previously, I received my B.S. in Mathematics from UT Austin, where I worked with Dr. Junfeng Jiao on AI systems for city-scale sensing, simulation, and decision support.
Please feel free to connect with me here if you'd like to chat.
