Bio

I am a research scientist at Meta. My research interests are at the intersection of AI, ML, and NLP.

Currently, I work on Meta's Modern Recommendation Systems (MRS) Team. At MRS, I develop AI models to improve video ranking on Facebook Reels and Instagram Reels, with a focus on long-term value optimization and retention modeling. My work helps users adaptively personalize their Reels experience, so that they can continually discover fresh, relevant, and valuable content.

Previously, I was a research intern on the AI Integrity Team at Meta, where I worked on language model explainability. Before that, I was an engineering intern on the Android Camera Team at Google, where I worked on image saliency detection.

I earned my PhD in computer science from the University of Southern California, advised by Prof. Sean (Xiang) Ren at INK Lab. During my PhD, I conducted fundamental research in ML and NLP, developing algorithms for model explainability and explanation-based learning. I earned my MSE in robotics from the University of Pennsylvania and my BS in electrical engineering from the University of Maryland.

Outside of work, I enjoy tennis, basketball, pickleball, skiing, and spending time with my family.
