During my PhD, I’ve built, contextualized and scaled technologies that support marginalized people working in Health & Agriculture.

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

    Created an AI model that CHWs can use to screen whether atrial fibrillation has happened or will happen to a patient in a given 60-day window using ECGs from a low cost, portable device. CVDHJ paper here in collaboration with AliveCor and UW Medicine.

  • Nudging Uptake of Clinically Valid LLM Chatbots in Urban India

    Quantified patients’ treatment expectations where local practices deviate from clinically validated guidelines, then designed LLM-enabled bots to shift preferences towards safe practices. JMIR submission here in collaboration with MSR India and Everwell.

  • Juxtaposing the Imaginaries & Realities of Integrating AI tools in Nepal

    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 in collaboration with UW Global Health.

  • Measuring the Performance of LLMs on Indic Language Postoperative Queries

    Interrogated 20 LLMs’ ability to respond to queries from Indic language speakers, paying particular attention to where and how they fail. Our NLP submission here in collaboration with MSR India.

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

    Created the first contactless system that can detect blood clotting status using the LiDAR sensors on smartphones with no attachments. Ubicomp paper here in collaboration with Shyam Gollakota and Justin Chan.

  • Charting the Landscape of Mobile Phone Use by Rural Tanzanian Farmers

    Surveyed 1014 agricultural households in rural Tanzania to quantify mobile technology access, use, and comfort in this marginalized population. CHI ’23 publication here in collaboration with Cornell Economics & IRDP.

  • Building and Deploying eKichabi v2 in 100 Tanzanian Villages

    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 in collaboration with Cornell Economics & IRDP.

  • Scaling the Impact of New Digital Public Goods with Intermediaries

    Ran focus groups with mobile money agents to outline the infrastructure needed to repurpose their intermediation skills to serve any digital public good. Then, piloted their intermediation of eKichabi v2. COMPASS ‘23 paper here in collaboration with IRDP.

  • Understanding Smartphone Supported Entrepreneurship in Periurban Tanzania

    Ran focus groups with 49 smartphone-supported entrepreneurs in periurban Tanzania to understand how they started and grew new businesses with the help of their smartphones. CHI ‘22 publication here.
