A Short Bio
I am an Associate Professor of Computer Science at UC Santa Barbara, co-director of the MIRAGE Lab, and affiliated faculty in the Four Eyes Lab. Before joining UCSB, I received my Ph.D. degree from the Department of Electrical Engineering and Computer Sciences at UC Berkeley, advised remotely by Prof. Ravi Ramamoorthi at UC San Diego. During my Ph.D., I worked at Walt Disney Animation Studios (2014), Autodesk (2015), Weta Digital (2016) and NVIDIA Research (2017) as an intern. Earlier, I obtained my bachelor degree in Computer Science from Tsinghua University in China in 2013, advised by Prof. Shi-Min Hu and Prof. Kun Xu.
Research
RT / offline Rendering
Appearance Modeling
Future Display Equip.
Emerging Technology
Ultimate Realism
My research is in Computer Graphics. During my Ph.D. career, I mainly aimed at rendering photo-realistic visual appearance (a.k.a. hard-core graphics) at real world complexity, building theoretical foundations mathematically and physically to reveal the principles of the visual world. I have brought original research topics to Computer Graphics, such as detailed rendering from microstructure, and real-time ray tracing with reconstruction. And I took the first steps exploiting Machine Learning approaches for physically based rendering.
As a young Computer Graphics researcher, my dream is to present people an interactive computer-generated world to live in, just like the ones in the movies The Matrix and Ready Player One. To achieve that, I come up with my own Rendering Equation, as you can see above. I am prudently looking for outstanding graduate students (details and FAQs) to work on related research topics, including but not limited to physically-based / image-based rendering, real-time ray tracing and realistic appearance modeling / acquisition. Let's work together, not to change the world, but to create one.
I am fortunate and proud to work with these phenomenal students:
Current PhD Student(s): Tao Huang, Zilin Xu, Songyin Wu, Zheng Zeng
Current MS Student(s): Minghao Huang, Liangfu Kang, Chuyan Zhang
Alumni: Yang Zhou (PhD, now at Meta), Junqiu Zhu (Postdoc, now at Shandong University), Lara Floegel-Shetty (MS, now at Apple), Shlomi Steinberg (PhD, now at U Waterloo), Jinglei Yang (MS, now at Amazon), Lei Xu (MS, now at Meta)

Misc
I am a huge fan of video games. When I was in primary school, it was this specific game that convinced me to take rendering and Computer Graphics as my lifelong career. I regularly hit Legend in Hearthstone. At UC Berkeley, we had a Hearthstone team and we made to the playoffs in the TeSPA Hearthstone Collegiate National Championship. I also enjoy battle royal games. I play Apex Legends and reached Diamond rank consistently.
I play piano a little bit, but classic only (with a National Piano Certificate of Level 10 in China, topmost for non-professional amateurs). I'm especially fond of Chopin's. Here are some short recordings of my home performance (F. Chopin: Waltz Op. 64. No. 2 in C-Sharp Minor, Nocturne Op. 9 No. 1 in B-Flat Minor and Op. 9 No. 2 in E-Flat Major). I'll upload more as my website continues to update.
My legal name spelling should be Lingqi Yan, and I only use Ling-Qi Yan for publications (due to some lab traditions at Tsinghua University). My name is pronounced as Ling--Chi--Yen, and here are some funny mistakes about how people usually call me (and I like them all).
"Lingqi Yan, first of his name, the unrejected, author of seven papers, breaker of the record, and the chicken eater." -- Born to be Legendary, by Lifan Wu @ UCSD.
