Wildlife ecology, management, and policy; Biodiversity conservation; Science outreach and communication
My group studies the effects of environmental change on the behavioral, population, and community ecology of wide-ranging wildlife. We are especially interested in the development of solutions to human-wildlife conflicts. We work with agency, university, non-profit, and private partners to make sure we are asking the right questions and making the best research contributions we can. We also work with photographers, filmmakers, artists, and others to communicate about science and conservation to the public. Our work is motivated by a global need for science and conservation solutions that promote both ecological integrity and human wellbeing, especially in working landscapes.
