Lifan Wu

I am Lifan Wu, a fifth-year PhD candidate at University of California, San Diego. My advisor is Prof. Ravi Ramamoorthi. I graduated from Tsinghua University in July 2015.

My research interest is physically based rendering, including sparse sampling and reconstruction of visual signals, realistic appearance modeling, and light transport. At Tsinghua, I worked at Graphics and Geometric Computing Group, advised by Prof. Kun Xu. In summer 2014, I worked as a research intern at Washington University in St. Louis, advised by Prof. Tao Ju.
