Brian L. Burke, PhD
Fort Lewis College

Brian Burke is a clinical psychologist whose principal academic interests include teaching, motivational interviewing, and terror management theory. Dr. Burke has a degree in college teaching and regularly attends teaching conferences, twice winning the Doug Bernstein Poster Award for innovative classroom ideas at the National Institute on the Teaching of Psychology (NITOP).

He has published several meta-analyses of studies evaluating the efficacy of motivational interviewing—an emerging treatment for substance use and other problem behaviors that combines the humanistic elements of client-centered therapy (Carl Rogers) with more active strategies (e.g., cognitive-behavioral therapy) designed to facilitate human change. He has also published several meta-analyses of terror management theory, which states that much of what we humans do may be a defense against our inevitable mortality. Dr. Burke originally hails from Montreal, Canada, and received his PhD from the University of Arizona in 2003, which is where he had the idea to take photographs of saguaro cacti to represent the different DSM disorders found in this textbook. He has been a licensed psychologist in Colorado since November 2004 and has served as assistant training director for the Student Counseling Center at Fort Lewis College. Dr. Burke lives in Durango, Colorado, with his wife, son, and Checkers the dog.
