I trained in educational psychology at the University of Utah where I developed the skills needed to conduct expert, comprehensive testing for questions about learning differences like learning disorders, intellectual disabilities, ADHD, and related challenges. I’ve also had training in diagnosing and treating a wide range of mental health conditions, including the co-occurrence of developmental differences and mental health conditions. My main area of expertise is in diagnosis for people with autism spectrum conditions across the lifespan, including a unique knowledge and skill in working with adults.

I have trained many graduate students and other professionals in these areas, as a professor in the Department of Psychiatry at the University of Utah. I have held positions in related areas for over 9 years at the University of Wisconsin, Madison. I have also been active in research, primarily in autism, with selected publications listed below.  I serve as a member of the executive committee for the American Psychological Association's Division 33, Intellectual & Developmental Disabilities/Autism Spectrum Disorder.

I have also had formal training in Mindfulness Based Cognitive Therapy and Mindfulness Based Stress Reduction programs.
