Aleksandr Razin

About me

I'm Aleksandr Razin, a Research Scientist at INSAIT and an ELLIS PhD student, advised by Dr. Jinjin Gu (INSAIT) and Prof. Marc Pollefeys (ETH Zürich). My research focuses on visual agents and generative world models for embodied AI.

Prior to this, I worked on video restoration and diffusion models at Huawei, founded a computer-vision startup, and built the agentic copilot at TradingView. I earned my M.Sc. in Machine Learning at ITMO University.
