CS Ph.D. Candidate @ National University of Singapore · Advisor: Prof. Bingsheng He

Hi! I build LLMs that read financial text and turn it into investment decisions, and I study the biases that bend their judgment.

Beyond finance, I work on LLM multi-agent systems (MegaAgent, ACL’25: a 590-agent fully autonomous system) and foundation model analysis (LLM DNA, ICLR’26 Oral). My work has appeared at ICLR, NeurIPS, ICML, ACL, EMNLP, COLM, and LOG, with several Oral presentations and an Outstanding Reviewer Award (EACL 2026).

I am always happy to chat about research, collaborations, PhD applications, or life choices. Reach me at persdre@gmail.com.
