I am currently a Ph.D candidate in Computer Science at CSE, Washington University in St. Louis, under the supervision of Prof. Tao Ju.
I earned my MS in Computer Science from Gatech in 2024, ME in Engineering from Tsinghua University in 2018. Please Check my CV.
My research interest includes 3D reconstruction, 3D computer vision and machine learning.
