Karkar Ravi

Hello! I am a PhD student in the School of Computer Science & Engineering at the University of Washington. I am advised by James Fogarty.

I am interested in designing, developing, and evaluating new personalized health data experiences that empower people to gain deeper insight and value from their data. Specifically, I focus on opportunities for individualized interventions that can be more effective and appropriate than one-size-fits-all population based interventions.
