Official Academic Profile: [En][中文]

I'm an Assistant Professor (百人计划研究员) at the College of Computer Science and Technology, Zhejiang University, and work closely with Prof Gang Pan and Prof Huajin Tang. I received my BEng (2011) and PhD (2017, supervisor: Prof Gang Pan) degrees in computer science from Zhejiang University. From 2018 to 2022, I was a Research Fellow at the ROSE Lab, Nanyang Technological University and worked closely with Prof Boxin Shi, Prof Xudong Jiang, and Prof Alex Kot.

I have co-authored over 80 peer-reviewed papers. I was a recipient of the ACM Rising Star Award (Hangzhou Chapter, 2024). I currently serves as an Associate Editor for Pattern Recognition (PR), IEEE Transactions on Cognitive and Developmental Systems (TCDS) , and Neurocomputing.

My research interests include neuromorphic computing, computer vision, and machine learning, with special emphasis on spiking neural networks (e.g., training methods, spiking LLMs) and neuromorphic cameras (e.g., event camera-based low-level vision). Recently, I have become particularly interested in hardware-software co-design for neuromorphic computing.
