Dr. Sturman is the co-coordinator of the Psychology program at the Queensbury branch campus, where he has taught many courses, including a seminar in Psychological Assessment. Dr. Sturman has developed several psychological tests, including the Mood Disorders Insight Scale (MDIS) and the Involuntary Subordination Questionnaire (ISQ), which have been linked to the course and outcome of mood disorders. He has also conducted research into the assessment of competency and developed a new method to evaluate the reliability of tests. His research findings have been published in well-regarded psychological journals and presented at major psychological conferences. Prior to his current teaching position, Dr. Sturman worked at the Self-Management Group as a consultant investigating the link between personality and performance in competitive environments, including sales and management positions at large corporations. His current research is primarily focused on the vulnerability of various personality styles to mental disorder as well as the evolutionary underpinnings of mental disorder.Dr. Sturman thanks his students, and in particular, Michelle Mann-Saumier, KylieMcKeighan, Joyalina David, Jeff Merrigan, and Jennifer Burch Dean for their work on his contribution to this book.
