Hello! I am a Postdoctoral Scholar in Computer Science & Engineering and Human Centered Design & Engineering at the University of Washington. I work with James Fogarty and Gary Hsieh. I am a member of the DUB group and the ALACRITY center.

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 have explored tools that:

  • support collaborative care management of patients with cancer and depression by integrating care managers, oncologists, psychiatrists, and administrators to treat depression in primary care settings
  • enable self-experimentation (n-of-1 trials) among people with irritable bowel syndrome (IBS) to identify their individualized food-based triggers
  • introduce a new form of self-monitoring in people with end-stage liver disease enabling them to better understand their chronic condition

My long-term goal is to empower people to gain an informed perspective of their individual health and well-being.

I received my Ph.D. in Computer Science & Engineering from the University of Washington. I am a recipient of the Three-Sixty Fellowship for computer science and engineering and numerous travel grants to present my research at premier conferences. My research has been recognized by CHI and DIS, and I have organized cross-disciplinary panels and discussions around tools for self-tracking at ICTD and QSC.
