My academic and practical training is in the social behavior of birds and mammals, with a special focus on highly social species like domestic dogs, crows and jays, primates, and killer whales. My background includes a Bachelor's degree in Biology from Millersville University (1980), a Master’s degree in Biology from Wake Forest University (1983), a Ph.D. in Zoology, with a specialization in animal behavior, from Colorado State University (1989), and professional credentialing as a Certified Applied Animal Behaviorist, the highest level of certification in dog behavior that is available. At the University of Washington since 1990, I am currently an Emeritus Research Professor in Psychology (Animal Behavior Program) where I teach and conduct research in complex social behavior and cognition of several animal species.
During my graduate training, I interned with Dr. Philip Lehner (Colorado State University) and was active in his behavior consulting business in Colorado, Animal Behavior Associates of Colorado. I started my own consulting business in companion animal behavior in 1999 and currently practice through Adaptive Animals, LLC with Dr. Robin Foster (AdaptiveAnimals.com). I perform in-home evaluations and treatments on behavior issues (80% aggression) in dogs, cats and parrots (averaging 45 cases/year) and advise on additional cases per year seen by my colleagues. In addition, I have participated in a number of legal cases as an expert witness, both Consulting and Testifying, and on cases involving both dog bites and dog tracking behavior. I have also been involved with the development of the professional certification program for applied animal behaviorists through our professional academic organization, the Animal Behavior Society (www.animalbehavior.org) and have served as a member of the Animal Behavior Society’s Executive Committee for many years.
