Curriculum Vitae

Short Bio

I am now a Starting Researcher of the GraphDeco group at Inria Sophia-Antipolis. Before that, I did my postdoc in the Smart Geometry Processing Group at University College London (UCL) working with Prof. Niloy Mitra. I got my Ph.D. degree from the University of Hong Kong in 2019 supervised by Prof. Wenping Wang and got my Bachelor degree from Shandong University in 2014.

Currently I am interested in 3D Shape Creation and Analysis, Sketch-based Modeling, Medical Image Processing, 3D Vision, and Geometry Processing.
