About
I am an ML/AI researcher and engineer with experience shipping production systems across LLM optimization, adaptive experimentation, causal inference, and financial ML.
Most recently, I was a Member of Technical Staff at TensorZero, a leading open-source LLMOps platform, where I designed and shipped algorithms for optimizing agents, including multi-armed bandits for adaptive A/B/n testing, top-k arm identification, and automated evaluation systems, grounded in rigorous statistical theory.
Prior to TensorZero, I spent four years at JPMorgan AI Research, most recently as AI Research Lead/VP, conducting research across adaptive experimentation, causal inference, algorithmic fairness, and uncertainty quantification, and shipping production ML models for pricing and causal inference applications.
I received my PhD in Statistics & Data Science from Carnegie Mellon University, where I worked with Edward Kennedy and Alexandra Chouldechova on problems at the intersection of causal inference and algorithmic fairness.
