Gecko

The Gecko family of individual-based simulators were my main research thrust at Yale. I've presented Gecko at a number of scientific conferences, mostly to those interested in individual based modeling, but some interested in the ecosystem dynamics. I authored and co-authored a number of papers. I've taken a very different approach than most to 'spatial' modeling - Gecko entities have extent and volume and mass, not just grid position.

Woods

launch Woods

Woods simulates northeastern U.S. forest growth with 3 tree species. Features disruptions (hurricanes, deer grazing, fires, etc.), landscape fragmentation, and mixed site quality. Based loosely on Sortie. Woods is primarily a teaching simulator, used at several universities. At Yale, it's used to teach Landscape Ecology.
