Hi! I am a PhD student at Georgia Tech working on 3D computer vision, advised by Prof. James Hays. I am currently also a research intern at Niantic Spatial. I am excited about Spatial AI: models that understand the 3D world from visual data. I enjoy working on research at the intersection of 3D geometry, deep learning, and optimization.

Prior to this, I worked on long-range perception problems for autonomous driving at Waymo. I have also been a student researcher at Google DeepMind. I earned my Master’s from Georgia Tech in 2020, during which I worked on SfM problems with Prof. Frank Dellaert. I was also part of a wonderful team from the RAIL lab that won the FetchIt! challenge at ICRA 2019.

Please feel free to send me an email if you’re interested in research collaborations!
