Dr. Allen's expertise rests in three general human-environment interaction arenas: rock decay, biogeomorphology, and humanistic geography. Specifically within these broad categories, he focuses his research on rock art management, biological soil crusts, and incorporation of fieldwork into pedagogy, respectively. He has published in several journals regarding each of these topics and presents widely at professional conferences. He currently serves as the Faculty Advisor for the Department's registered student organization and the Colorado Geographic Alliance Strategic Planning Committee, and engages P-12 teachers with real world field experiences every chance he gets.
