I’m a second-year Computer Science PhD student at Northwestern University, working with Prof. Marcelo Worsley in the tiilt Lab on designing and evaluating AI-augmented multimodal interactive systems. My current research focuses on building LLM-powered analytics dashboards and conversational agents to support data-driven, context-aware scaffolding for communication and collaboration.

My past projects include uncertainty quantification in human-AI interaction . My undergraduate research involved uncertainty representation & reasoning, causal inference, and preference elicitation & aggregation for decision support systems [prototype].
