In my doctoral research, I’ve examined socio-technical systems to design, contextualize and scale technologies that support marginalized people in the domains of Health & Agriculture.

  • Building AI Models for Health Worker Led Atrial Fibrillation Screening in Rural Nepal

    Collaborated with AliveCor & UW Medicine to create an AI model that predicts CHWs can use to screen whether atrial fibrillation has happened or will happen to a patient in a given 60-day window using mobile, 6 lead ECGs from low cost, portable ECG devices. CVDHJ paper here.

  • Nudging Uptake of Clinically Valid Treatment using LLM-enabled Chatbots in Urban India

    Worked with Bill Thies & Mohit Jain at Microsoft Research India to quantify patients’ treatment expectations where the local health system deviates from clinically validated practices, then designed LLM-enabled bots that shifted preferences towards safe practices. JMIR submission here.

  • Juxtaposing the Imaginaries & Realities of Integrating AI tools into the Nepali Health System

    Collaborating with UW Global Health & the Nepali Health Department, I collected health leaders’ imagined futures of diagnostic AI tools and juxtaposing them with the realities of creating and maintaining the tools within the extant health system. CSCW submission here.

  • Measuring the Performance of LLMs on Indic Language Postoperative Queries

    Collaborating with MSR India, I interrogated 20 LLMs’ ability to process and disseminate complex health information in response to queries from Indic language speakers, paying particular attention to where and how they fail. Our NLP submission here.

  • Using Smartphone LIDAR to Detect Clotting From A Single Drop of Blood

    Collaborated with Shyam Gollakota and Justin Chan to create the first contactless system that can enable community health workers to detect blood clotting status using just the LiDAR sensors on their extant smartphone hardware. Ubicomp paper here.

  • Charting the Landscape of Mobile Phone Access and Use in Rural and Periurban Tanzania

    I surveyed 1014 agricultural households in rural Tanzania to quantify mobile technology access, use, and comfort in this marginalized population. Further, I held focus groups with 49 smartphone-supported entrepreneurs in periurban Tanzania to understand how they started new businesses with the help of their smartphones.

  • Building and Deploying eKichabi v2 in 100 Tanzanian Villages

    With researchers at Cornell University, I designed, developed and deployed eKichabi v2, a searchable, lightweight, offline directory of agriculture-related enterprises accessible via USSD and Android to 10,000 farmers in rural Tanzania. CHI ’23 publication here.

  • Scaling the Impact of New Digital Public Goods with Mobile Money Agents as Intermediaries

    With researchers at the Tanzanian Institute of Rural Development and Planning, I ran focus groups with mobile money agents to outline the infrastructure needed to repurpose their intermediation skills to serve any new digital public good. Then, I piloted their intermediation of eKichabi v2. COMPASS paper here.
