I am a Principal Applied Scientist at Microsoft AI, focusing on agentic AI for search systems. My work develops safe, human-aligned multimodal LLMs that learn from feedback while ensuring trustworthy deployment at scale.
Previously, I worked at Pinterest Labs, pioneering bias evaluation frameworks and red-teaming methodologies for LLMs and image generation models in production. I also established Pinterest’s fairness evaluation and mitigation frameworks across recommendation systems. Prior to Pinterest, I completed my PhD at Cornell University under Thorsten Joachims, establishing foundational work in fairness for ranking and recommender systems. I also completed research internships at Google Brain, Facebook Research, and Microsoft Research.
My research bridges AI safety theory with practical deployment, publishing at top venues (NeurIPS, ICML, SIGIR, KDD, FAccT) while shipping state-of-the-art responsible AI systems serving hundreds of millions of users. I also serve as Area Chair for NeurIPS and ICML, and co-taught the NeurIPS 2022 tutorial on responsible ML.
