Dr. Hessl's clinical interests involve cognitive, emotional, and behavioral evaluation of children, adolescents and adults with neurodevelopmental disorders, especially those with fragile X syndrome, autism spectrum disorders, ADHD, and learning disabilities. He also has expertise in developmental psychopathology, particularly mood and anxiety disorders, in infants and young children. Dr. Hessl received his Ph.D. in Child Clinical Psychology from the University of Washington in 1997, which included a clinical internship at Stanford University, and received postdoctoral fellowship training at the UC Berkeley Institute of Human Development during 1997-1998. He has focused his recent research on genetic, environmental and hormonal contributions to cognition and behavior in children with fragile X syndrome. Dr. Hessl has developed a laboratory to investigate the emotional psychophysiology of children with neurodevelopmental disorders at the UC Davis MIND Institute, where his work currently concentrates on autism, fragile X syndrome, and most recently individuals who are carriers of the fragile X gene. Several of the measures developed in his laboratory are currently being used as experimental outcome measures in clinical trials of individuals with neurodevelopmental disorders.  He also conducts collaborative studies with other researchers, investigating brain imaging, molecular genetics and neuropsychology in an effort to understand links between genetics, brain function and behavior.
