Jack uses a variety of sampling methods and quantitative approaches to investigate the relationship between people and wildlife. He is particularly interested in understanding the behavioral and ecological responses of carnivores to changes in their foraging opportunities, primarily due to human-induced environmental change or modifications in human-wildlife management practices. He is also active in advancing the use of stable isotope analysis in wildlife research. For example, he and Jake Ferguson have been on the forefront of advancing statistical models used to estimate the diets of animals using stable isotopes. Although he is often motivated by his basic research interests, he identifies as an applied wildlife ecologist. As such, informing wildlife conservation, management, and policy is often the main goal of his work.
