Sreehari Rajan

MS by Research @ IIITH

I am a researcher working on 3D computer vision, 3D human-scene interaction, and embodied AI. I am pursuing an M.S. by Research at the Machine Learning Lab (MLL), IIIT Hyderabad, advised by Dr. Charu Sharma. I study how to model 3D humans and their motion, and how people interact with objects and scenes, so that embodied agents can perceive and act in the physical world.
