Hey! I am Pujith Kachana, an Applied Scientist at Wayve. Previously, I was a Robotics Masters student at Carnegie Mellon University. I am advised by Dr. Ji Zhang and Dr. Wenshan Wang, and affiliated with the Field Robotics Center and the AirLab. I am primarily interested in embodied intelligence, particularly spatially-grounded perception and reasoning. My current work is focused on 4D geometric scene understanding and 3D semantic representation learning.
I am currently on the Foundation Model team at Wayve, working on spatial intelligence for autonomous driving. Previously, I have worked at Amazon Robotics as an Applied Science Intern and a Software Development Co-op.
Before my time at CMU, I obtained my BS in Computer Science from Georgia Tech, where I worked with Dr. Danfei Xu on deformable manipulation and Dr. Ada Gavrilovska on secure visual servoing.
Ultimately, I want robotic agents to be able to understand and reason about the physical world in an inherently embodied, 3D manner, much like humans. My goal is to develop agents that not only understand 3D geometry, motion, and semantics but can also ground and fuse multimodal concepts, such as language, into this physical world. Specific research topics of interest include 4D reconstruction, scene flow, and visual-language reasoning.
