About Me

I am currently pursuing my final-year Ph.D. in the Department of Computer Science and Technology at Zhejiang University, where I began my program in the fall of 2021. I am fortunate to be under the supervision of Prof. Duanqing Xu and Prof. Yabo Dong. Moreover, I am currently visiting the College of Computing and Data Science at Nanyang Technological University, under the supervision of Prof. Han Yu.

My primary research interests lie in sensor-based time series data mining, specifically focusing on the development of large language models (LLMs) for time series, generative models, and transfer learning.
