Research Topics

I am broadly interested in 3D computer vision and geometric deep learning. My current research focuses on incorporating physics and geometric priors for visual generation.

Previously, I worked on shape analysis and generative modeling in EM imaging ( [ PyTC]) and CT imaging (Rib Analysis). Additionally, I design and build robots for competition events and medical usage. [Check the robots I built. ]

Hobbies

I enjoy film photography and movies. I’ve spent a wide spectrum of my time reading philosophy (my favorites are Socrates and Diogenes) and physics (I idolize Richard Feynman). Catch me at SEC if you’d like to chat :) Fun fact: I used to be a competitive FPS player (CS:GO Faceit 10, 2017–2023; CS2 NA server Top 1000, 2024).
