Supporting health and happiness through technology

I am an Assistant Professor at Drexel University in the College of Computing and Informatics. My research areas include human-centered computing, computer supported collaborative work, and health informatics. I lead the Health and Happiness Design Lab (H2Design Lab) (website is under construction).

My current research projects include using conversational agents and other mobile and web-based technologies to improve health in everyday settings. I also study how various stakeholders, including human subjects, Institutional Review Board, and researchers perceive about what is sensitive personal information, and how this information should be managed in the context of digital technology use. I have been PI of NSF and NIH funded projects in improving information quality of online health communities and designing and evaluating acoustic-sensor based awareness system for family health. I serve as Steering Committee for ACM CSCW (2019-), Committee on Human Research at American Psychological Association (2020-2022), Best Paper Nomination Committee for CHI, and program committee for ACM CHI, AMIA, and EAI Pervasive Health conferences. Here’s my CV (Updated Winter, 2021):

Diva Smriti (PhD student, Drexel) with Rahil Rathod (IS Masters, Drexel) developed and user tested TAMICA, which uses motivational interviewing technique to help parents eat healthier with children.

Rahil Rathod (IS Masters, Drexel) examined how much control developers have over user data during the chatbot development.
