avatar I am a PhD student at TTIC advised by Greg Shakhnarovich in the PALS Lab. I primarily work on 3D computer vision and generative modeling. Before coming to TTIC, I received my Master of Computer Science from Washington University in St. Louis, advised by Ayan Chakrabarti. I got my Bachelor of Mathematics from Sun Yat-sen University. I have interned at Adobe Resarch, Meta Reality Labs and Megvii.
