My goal is to develop technologies that improve healthcare for everyone. Towards this, I develop novel data-driven technologies and AI models by rigorously studying their high-stakes and complex clinical applications. I focus on data and models for monitoring heterogeneous chronic conditions, where symptoms present diversely, and where the ways in which health data is collected and managed vary. These variations make it challenging to develop technologies that reliably and equitably support clinical care. My research is inherently interdisciplinary, and sits at the intersection of human-computer interaction (HCI), ubiquitous computing, responsible AI, and digital health.
