Dennis (Dongmin) is a quantitative ecologist at the Smithsonian Conservation Biology Institute's Conservation Technology and Innovation (CTI) and the lead data curator for the MoveDisease Archive. His research focuses on developing and applying statistical tools to infer behavioral processes from ecological data. Currently, he focuses on developing technical and governance frameworks to integrate bio-logging and disease data to understand pathogen-host interactions better.

Since 2022, Dennis has worked alongside CTI scientists Autumn-Lynn Harrison, Jared Stabach, Katherine Mertes, and Lacey Hughey as a pre-Doctoral fellow and intern on multiple projects, including developing and applying hidden Markov models to infer disease progression in scimitar-horned oryx reintroduced into central Chad.

Dennis earned his B.A. in Statistics from the University of Minnesota, Morris, and his Ph.D. in Ecology, Evolution, and Behavior from the University of Minnesota. He previously held postdoctoral positions at the University of Minnesota and Harvard University before joining the Smithsonian.
