Dr. Wall received her B.A. in Psychology from UCSD and her Ph.D. in Clinical Psychology from the Joint Doctoral Program between SDSU and UCSD. She completed an internship and a postdoctoral fellowship in Clinical Psychology at UCSF where she specialized in substance abuse services. She is a licensed psychologist at VA San Diego Healthcare System (VASDHS). Dr. Wall is Associate Vice Chair, Academic Affairs for the Department of Psychiatry, Associate Director of the SDSU-UCSD Joint Doctoral Program in Clinical Psychology, and Co-Director of the Interprofessional Advanced Fellowship in Addiction Treatment at VASDHS. Her research is focused on understanding how substance use problems and comorbid behaviors develop and manifest themselves. To pursue this goal, she studies racial/ethnic groups and families with varying patterns and consequences of substance use. The majority of her research has focused on advancing our understanding of two developmental pathway models for alcohol and other substance use problems – the pharmacological vulnerability model, which hypothesizes variations in responses to alcohol affect the likelihood of consuming large amounts of alcohol and developing alcohol problems, and the deviance proneness model, which posits externalizing behavior, high sensation seeking, and low behavioral control in childhood result in later substance use problems. This research focuses on both genetic and environmental factors to examine the nature of gene-environment interplay over development.
