I am an Assistant Professor in the Computer Science and Engineering department at Texas A&M University. Previously, I was a postdoc in the CSE department at UC San Diego, where I worked with Ravi Ramamoorthi. I finished my Ph.D. in the ECE department at UC Santa Barbara under the supervision of Pradeep Sen.

News
  1. I will serve as the technical papers committee for SIGGRAPH 2025.
  2. One paper accepted to ECCV 2024.
  3. Received the 2024 Frontiers of Science Award for LLFF (SIGGRAPH 2019)!
  4. Received the TEES Young Faculty Fellow Award!
  5. Logan (Xilong) successfully defended his PhD thesis!

Research Interests

My primary research interests are in computer graphics with an emphasis on computational photography and rendering. Specifically, in recent years, I have focused on developing machine learning techniques for image synthesis in these two fields. Overall, my goal is to develop practical systems in a variety of computational photography and rendering applications with the goal of representing the world around us accurately.
