My research interests broadly apply to the realm of wildlife management with a particular focus on resolving human-wildlife conflicts.  Expanding human populations have led to increasing interaction with a variety of wildlife species including rodents, birds, and predators.  In many situations, conflict occurs.  Many options can exist for mitigating this conflict depending on each specific situation.  It is my goal to develop strategies to effectively reduce this conflict while having the least impact on human and wildlife populations.  Past and current research projects that relate to human-wildlife conflict resolution include developing an integrated pest management program for reducing California vole damage to artichokes, identifying effective strategies for managing pocket gophers in wine grapes and alfalfa, and developing a much needed monitoring and management program for black bears in Rocky Mountain National Park, Colorado.  I also have broader interests in other aspects of wildlife management.  Examples of such past studies include population monitoring and habitat assessments of a variety of predator and ungulate species including American martens, black bears, raccoons, Virginia opossums, striped skunks, and elk.
