Josh grew up in Chicago and developed an interest in ecology through backyard birds and summer vacations to national parks across the western US. He began his research career at the University of Montana, studying songbirds and several species of large mammals, including the leopards and tigers of Bhutan. After sticking around in Montana following his BS, he moved to the University of California, Riverside to complete his PhD, studying coexistence in the freshwater fish communities in the mountain streams of Trinidad. In his research projects, he uses strong quantitative techniques to unravel the complexity and diversity of ecological systems. When not in the field or crunching numbers, he enjoys running, biking, hiking and taking pictures.
