Research Interests: We study brain activation patterns involved in typical and impaired socio-emotional development (for example, social interaction with other people, reading people’s emotions, and reacting to people’s facial expressions). In particular, we are interested in understanding factors (e.g., genetics, social, family) that affect brain function in children and adolescents without disorders, in addition to youth with autism, depression, anxiety, and irritability symptoms. To accomplish this, we use functional MRI, functional connectivity, and genetic, behavioral, and neuropsychological tools. Dr. Wiggins is happy to talk with any interested students about these research topics.

Johanna Walker
Doctoral Student
Email: jcwalker@sdsu.edu
Career Goals: I am working towards my Ph.D. in clinical psychology in the SDSU/UCSD joint doctoral program with a focus on experimental psychopathology. I am planning to pursue a career in independent research in a multidisciplinary academic setting in the future.
Research Interests: I am interested in the neural correlates of cognitive biases and emotion dysregulation that influence the development and maintenance of psychopathology in youth. Specifically, I am interested in using multimodal assessments (e.g., neural, physiological, cognitive, socio-emotional) to examine how these mechanisms explain the manifestations of issues, such as changes in attention, memory, and information processing, that contribute to the experience of internalizing disorders and suicidal thoughts and behaviors.
