Tianpei Gu

Member of Technical Staff @ Lexica
San Francisco, California

I’ve been working on Generative Model since 2020 with both academic papers and product deployment in related topic. Currently, I’m a Member of Technical Staff at Lexica working on AIGC(diffusion model, GPT). I obtained my Master degree at UCLA where I had great fortune to work with Prof. Bolei Zhou. Prior to my Master study, I did research at Intelligent Vision Group (IVG), Tsinghua University, under the guidance of Prof. Jiwen Lu and Dr. Guangyi Chen. I also had an amazing time at SenseTime Research in the topic of GAN and latent space. In December 2020, I received B.S. degree in Computer Science and Mathematics at the University of Maryland.

My research interest is in Computer Vision, especially Generative Models, Diffusion Models and Human Motion Generation.


Jun 1, 2023 I will join Lexica as a Member of Technical Staff.
