I'm interested in how life history traits mediate species interactions, particularly in highly seasonal and rapidly changing environments of the Arctic and alpine regions of Africa. This research touches on elements of community, landscape, and behavioral ecology, and has recently focused on gelada monkeys and large Arctic herbivores. In conjunction with this research, I'm developing and testing applications for near-surface remote sensing platforms and the data they can generate.  Themes include long-term quantitative time lapse photography, non-invasive morphometric scanning, and the deployment of small unmanned aerial systems (sUAS) designed for mapping and animal censuses in remote areas.
