About

I am a Postdoctoral Research Associate in Department of Computer Science, Dartmouth College, working with Prof. Andrew Campbell. Previously, I received my Ph.D. in Department of Computer Science and Technology at University of Cambridge, advised by Prof. Cecilia Mascolo.

I develop foundation models for longitudinal and multimodal health sensing data, spanning wearable sensors, physiological signals, and electronic health records. Real-world health data are heterogeneous and incomplete, with sensor configurations, available supervision, and population distributions varying substantially across datasets and deployment settings. My research addresses these challenges through pretraining across heterogeneous datasets, domain adaptation under distribution shift, and large language model (LLM) enhancement for aligning sensing representations with language and reasoning over long-term health histories. I design model architectures and rigorous evaluation frameworks that turn heterogeneous health data into reliable health insights.
