Biography

I am a first-year PhD student in Mathematics at Imperial College London, supervised by Professor Kelly Zhang (Co-supervised by Prof. Andrew Duncan). Before joining Imperial, I earned an MSc in Applied Statistics from the University of Michigan, Ann Arbor in 2024 and a BSc in Mathematics from National Tsing Hua University in 2023.

I was fortunate to serve as a research assistant with Dr. Ming-Chung Chang at the Institute of Statistical Science, Academia Sinica during July–August 2023 and January–August 2025, and as a visiting scholar from May–August 2024.

For more details about my academic background and experience, please refer to my CV.
