Clinical and Public Health Applications
My computational work is grounded in real-world clinical and public health challenges, with a strong focus on last-mile execution and deployment. I also collaborate closely with public health and clinical communities to support research adoption.
Deployed Public Health Monitoring
Detecting events from millions of data streams in real-time.
The FlaSH system is deployed at Carnegie Mellon University and has been used for over 2 and a half years to monitor large scale data streams for anomalies.
Public Health Tooling
Agentic Perspectives for Population Modeling/Decision Making Tools
Statistical methods such as Monte Carlo modeling can support decision-making in public and population health, including resource forecasting under uncertainty.
Rare Disorders and Geospatial Variability
Addressing anomalies and variability
Neglected diseases and disorders can appear as anomalies in data. They can be detected and monitored using anomaly detection theory.

✍️ Cases2Beds: Project lead for a tool to provision hospital beds, developed in collaboration with the Allegheny County Health Department and shared with several other county public health departments during the COVID-19 Pandemic. Presented on 01/08/2020 at the COVID-19 Trends and Impact Surveys Data Users Meeting. https://delphi.cmu.edu/blog/2021/03/10/cases2beds-a-case-study-in-actionable-intelligence/
✍️ Fulbright Urban Planning & Sustainable Design Award, Singapore, National University of Singapore. IoT and Multimodal data for health. I developed a suite of micro/macro modules (including deep-learning models that use audio, visual, and spatiotemporal input data) designed to work together and assist users in designing urban spaces that are unappealing to mosquitoes.
