I invent mathematical algorithms, build statistical models, and write robust software to maximize insights from data.

Associate Research Scientist
Biography
Professionally, I am a data scientist in the most precise sense: I build quantitative algorithms, models, and inference tools with the utmost rigor and care to extract real understanding from data. My primary academic focus is the emergence of individual-scale immune functioning and its population-scale consequences from the dynamic interactions of cells and molecules. This broad theme has informed a variety of my study areas, including evolutionary processes, spatial tumor architecture, and vaccination response, as I have advanced from a Ph.D. student at Princeton University to a post-doctoral researcher at the NIH to a data scientist at the CDC to an Associate Research Scientist here at the Yale School of Medicine. Personally, my passions range more broadly, including my Christian faith, my family and community, the great outdoors, all things athletic, and much more.
