Currently I am seeking available Ph.D. position, feel free to reach out to me if you would like to discuss potential opportunities.
I hold an M.S. degree from Cyberspace Security Lab at Zhejiang University. During my time there, I had the privilege of being mentored by distinguished professors Prof. Zhongjie Ba and Prof. Kui Ren.
My academic journey has been enriched by diverse experiences, including an internship at Microsoft Research. Under the expert guidance of Shuang Ma, I had the opportunity to delve into advanced researches in representation learning and contribute to innovative projects.
Currently, I am passionate about:
- (Primary) Generative Model and 3D reconstruction: efficiency, theory and its application to various domains.
- Perception for human activity understanding: self-supervised learning method that improves egocentric video understanding ability.
- Security problem of AI - Forgery detection: detecting and identifying fake (AI generated) content.
