Haolin Xiong

I'm a PhD student in Computer Science at the University of Southern California - Institute for Creative Technologies (USC-ICT), advised by Assistant Professor Yajie Zhao.

Previously, I earned my M.S. in Electrical and Computer Engineering from UCLA, where I was advised by Professor Achuta Kadambi and Professor Lin Yang. I also hold an M.S. in Business Analytics and dual B.S. degrees in Computer & Systems Engineering and Economics from Rensselaer Polytechnic Institute.

Research

My research interests broadly span 3D vision and perception, with occasional work on 2D vision models such as generative foundation models. Recently, I have been focusing on 3D scene understanding using 3DGS, along with its potential applications in robotics and VR.
