I am an AI Researcher at Millennium Management. My work focuses on researching NLP signals for systematic equity strategies and building AI systems that emulate fundamental research at scale.

Previously, I was a Senior AI Researcher in BlackRock’s Investment AI Group, where I developed sentiment signals for live systematic equity strategies and trade execution, machine learning models for real-time corporate bond pricing, and multi-agent LLM systems for investment research, portfolio management, and trading. Before that, I worked as a Data Scientist at Intelligencia AI, building NLP and machine learning models to identify emerging areas of innovation in clinical research. I began my career as an Analyst in BlackRock’s Aladdin Business.

I earned my MS in Data Science from Harvard University in March 2021 with a GPA of 4.0. At the Data to Actionable Knowledge (DtAK) lab, I conducted research on uncertainty estimation for deep learning. I previously graduated first in my class with a BS in Computer Science and Mathematics from the University of Edinburgh.
