About

I am a research scientist in Meta's Applied AI organization, where I work on data-centric methods for evaluating and improving AI models, agents, and auto-research workflows through expert feedback, human-in-the-loop optimization, and data-efficient learning. Previously, I was on the Adaptive Experimentation team in Meta's Central Applied Science, where I developed Bayesian optimization and adaptive experimentation methods for turning human feedback, preferences, and behavioral signals into reliable evaluation and optimization signals for AI platforms and other large-scale systems.
