Bio

Iā€™m a fifth year PhD student in the Machine Learning Department at Carnegie Mellon University advised by Pradeep Ravikumar. My research centers around statistical machine learning, with a focus on developing principal algorithms for interpretability and Self-Supervised Learning. I interned at Amazon as an applied scientist, where I worked on large language models for tabular data and recommender systems.

Previously, I completed my M.S. degree in Computer Science & Information Engineering (CSIE) at National Taiwan University (NTU). I was a member of the Speech Processing Lab working with Lin-shan Lee and Prof. Hung-yi Lee, working on speech recognition and multi-label classification. During my undergrad years, I pursued a dual major in Electrical Engineering and Mathematics at NTU.
