Research


I am on the job market seeking a research industry position!

I am particuarly interested in AI research positions in the finance, fintech, and government/regulatory space. Particular applications of interest include (but are not limited to) real-time payments and financial crime risk mitigation.

About Me

Hello! I am a final year PhD Candidate in computer science & engineering at the University of Michigan. I am advised by Michael Wellman as a member of the Strategic Reasoning Group.

I leverage artificial intelligence and data to gain insights into complex phenomena.

My dissertation research lies at the intersection of computer science and economics. I apply artificial intelligence to study strategic decision making in financial networks. I gather data from simulation of agent-based models and use empirical game-theoretic analysis (EGTA) to reason about the decision making of various network participants. I aim to understand how strategic choices are made and the subsequent impacts of those decisions on the network. I have studied topics in debt cancellation, real-time payments, and financial fraud.

Prior to graduate school, I applied data analysis and machine learning methods to predict emergency room visits using cancer patient data and to predict events from social media data. As an undergraduate student, I attended the University of Massachusetts Amherst from which I obtained degrees in computer science and economics, as well as a minor in Chinese. My honors thesis, advised by Brendan O'Connor and Arindrajit Dube, applied time series forcasting to Google trends data for predicting state unemployment rates.

Research Interests

AI: computational economics, multi-agent systems, empirical game theory, applications of machine learning

Finance: real-time payments, fraud, systemic risk
