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.

Academic Advisors

• I am extremely fortunate to have been advised by Dr. Ming-Chung Chang, an Associate Research Fellow at the Institute of Statistical Science, Academia Sinica, during my senior year as a Mathematics student. He has guided my journey into the field of statistics from then until now.
• During my master’s studies, I am very pleased to be advised by Prof. Raed Al Kontar, an Associate professor at the Department of Industrial and Operations Engineering, The University of Michigan, Ann Arbor. We collaboratively developed two papers on sequential decision-making, which sparked my interest in this field.
