Current research.

Collaborative Care.

I design and develop technology-enhanced collaborative care systems to support patients with cancer and depression and their care team. I led the preliminary field research (multi-site, multi-stakeholder interviews and contextual inquiry) that revealed the parallel journeys that patients with cancer and depression experience and additional challenges and tensions that occur at the seams of the two journeys.

Digital Inequalities.

I examine the widening of digital inequalities associated with the COVID-19 pandemic by measuring shifts in 50+ billion web search interactions across 25,000+ US ZIP codes. I leverage a holistic framing inspired by the Social Determinants of Health and Maslow’s Hierarchy of Needs and a carefully controlled data analysis methods to isolate the effects of the pandemic and socioeconomic factors on the changes in web search behaviors across a spectrum of human needs. The analysis reveals that the more vulnerable subpopulations experience additional burden and barriers to accessing critical digital resources during the pandemic.

Workplace Wellbeing.

I design and develop integrated systems that provide just-in-time and personalized wellbeing interventions to help information workers find time to engage in self-care activities during their intense and stressful workday, based on measurements of workplace stress through passive sensing of physiological, affective and behavioral signals and self-reflection. I collaborate with clinical psychologists to understand how stress manifests over time, how different modes of self-care engagement mediates stress regulation, and how to design systems that help people find their wellbeing balance.
