I'm a 4th year PhD student in Information Retrieval at UMass Amherst, supervised by Hamed Zamani. My research focuses on conversational search and proactive language models. I'm also the founder of Naget, building the next generation of personal instruction-based search.

I've gained industry experience through internships at Amazon (generative ranking), Netflix (conversational search), and Adobe (multi-step dense retrieval), along with prior roles at Ro5 (biomedical knowledge graphs), NUS (fact-checking systems), Plural AI (semantic search for finance), and Donaco (contextual recommendations).

My goal is to advance multimodal content organization & discovery by addressing foundation model limitations in efficiency, robustness, and resource constraints.

Interested in collaborating on or investing in next-generation search technology? Let's connect.
