Ph.D. Candidate, Electronics Science and Technology · Zhejiang University

My research sits at the intersection of generative modeling and efficient AI systems, with a focus on controllable video generation and editing for diffusion/Video DiT models.

About

I am a direct Ph.D. student in Electronics Science and Technology at Zhejiang University, advised by Prof. Kejie Huang.

My research lies at the intersection of generative modeling and efficient AI systems. I study controllable video generation and editing for diffusion/Video DiT models, as well as efficiency techniques such as model compression and inference acceleration.

Before focusing on AI algorithms, I was trained in Microelectronics Science and Engineering. This background allows me to approach generative models from a system perspective, bridging algorithm design with efficient hardware-aware deployment.
