Ravi Karkar

Assistant Professor

My research focuses on designing, developing, and evaluating tools that can enable people to gather data and interpret personal aspects of their medical condition in the context of their day-to-day lives. Specifically, I focus on opportunities for individualized interventions that can be more effective and appropriate than one-size-fits-all population-based interventions. I collaborate closely with clinical researchers to build targeted tools to support patients in better understanding and managing chronic conditions. I have also contributed a domain agnostic framework and approaches towardbetter design of personal health technologies.

An overarching themes across the tools that I build is a focus on translating the research. I am interested in taking the research from lab-studies in to the hands of the individuals who need it.
