Gemini Omni Flash released at Google I/O 2026.
Weixi Feng (冯蔚熙)
I am a Research Scientist at Google DeepMind, working on Veo and Gemini Omni. I have done research on controllable visual generation and world modeling. I obtained my Ph.D. in CS from the UCSB NLP group, where I was advised by Prof. William Wang. I have worked/interned at Amazon AGI, NVIDIA Research, and Adobe Research.
I have spent wonderful years in Beijing, Hong Kong, and SoCal, and I am now based in Mountain View, CA.
