About Me
I specialize in distributed systems, cloud infrastructure, and systems performance. My research interests include privacy-preserving healthcare systems, federated learning for clinical applications, and medical AI diagnostics.
I act as a technical owner and decision-maker for complex initiatives, leading zero-to-one efforts and guiding cross-functional teams. I balance hands-on system design and implementation with mentorship, stakeholder alignment, and delivery of durable, production-grade solutions.
I serve as Associate Editor for IEEE Internet of Things Journal and npj Digital Medicine (Nature Portfolio). My published work spans federated learning, medical imaging, IoT security, and cloud systems.

Open Source Contributions
- NVIDIA (NVFlare federated learning framework) — Fixed a silent correctness bug in the edge training simulator that was wiping optimizer momentum state between batches and degrading model convergence on every run that used momentum, Nesterov, or weight decay
- Grafana Labs (Grafana) — Added a colorblind-safe color palette for data visualizations, making dashboards readable for users with red-green color vision deficiency
- Prometheus (CNCF-graduated monitoring system) — Added a delete-series admin page to the Prometheus user interface, exposing series deletion that was previously only reachable through the admin API
- U.S. Department of Health and Human Services (Simpler Grants, the grants.gov next-generation site) — Fixed 404 pages that were returning HTTP 200, restoring correct status signals for search engine indexing and uptime monitoring
- Expedia Group (Bull Java bean transformer library) — Fixed a long-standing field mapping bug where primitive fields mapped into nested objects raised MissingFieldException, using ThreadLocal to preserve root source context across recursive transformations
- NVIDIA (NVFlare federated learning framework) — Added model and dataset caching across federated learning rounds in the Hello Flower examples, removing redundant per-round initialization
- Huly Platform (open-source collaboration platform) — Added spellcheck support to the text editor components used across the platform
