Ziyang Leng

CS PhD @ UCLA


I’m a first-year CS PhD student at UCLA, advised by Prof. Bolei Zhou. Before that, I earned my bachelor’s degree from SUSTech and my master’s degree from UCLA.

My research interests lie in computer vision and machine autonomy, including perception, generation, and embodied AI.

I’ve worked on autonomous driving, representation learning, image/video generation, and trajectory simulation.
