PhD Student, University of Washington
Department of Computer Science and Engineering

I am a PhD student working with Shyam Gollakota in the Mobile Intelligence lab.

My research focuses on building intelligent mobile and embedded systems for computational health and large-scale environmental sensing.

I am a co-founder of Wavely Diagnostics, a company that is leveraging my research in mobile health to make pediatric healthcare more accessible.

I was the PI for a successfully completed NIH SBIR grant and now am a co-investigator for an NIH R21/R33 grant proposal on bringing universal newborn hearing screening to Kenya.

I earned my Bachelors degree with high honors in computer science and digital arts from Dartmouth (2015).

Research impact

  • My work on detecting ear infections using smartphones has been commercialized by Wavely Diagnostics where I am a co-founder. This technology is now FDA-listed and is available to select early access healthcare systems.

  • My earable device for low-cost newborn hearing screening has been presented to Kenya’s Ministry of Health. It has led to a larger effort called TUNE to bring universal newborn hearing screening across Kenya.

  • My work on contactless cardiac arrest detection using smart speakers has been licensed to Sound Life Sciences, which has recently been acquired by Google.

  • I led CovidSafe/CommonCircle (now WA Notify), a COVID-19 contact tracing and symptom tracking app, which became part of official efforts by the WA Department of Health to manage the pandemic.
