I value honesty in how I treat people and how I conduct research.

Probability · Optimization · Financial markets

I’m an undergraduate at Tufts University studying Applied Mathematics and Quantitative Economics, with a minor in Computer Science.

I’m interested in probability, optimization, and how mathematical models help us understand financial markets.

Through my internships at Jinge Asset Management and independent projects, I’ve worked on equity signals, portfolio optimization, and market-making simulations. I enjoy turning a question into a model, testing its assumptions, and understanding where the results hold up—and where they don’t.

I value honesty in how I treat people and how I conduct research. In my work, that means being explicit about assumptions, reporting negative results, and acknowledging what a model cannot tell us.
