Dr. Aaron Fisher received his Ph.D. in Clinical Psychology from Pennsylvania State University and completed his clinical internship at the VA Palo Alto Healthcare System. Before joining the faculty at UC Berkeley, he was a postdoctoral fellow at Stanford University.

His research focuses on treatment personalization, particularly the use of self-reported data to guide individualized treatment selection and optimization. His lab has made significant contributions to personalized machine learning and person-specific prediction models.

Dr. Fisher's work spans substance use, dimensional and DSM-defined psychopathology, and psychophysiology. He also explores metascientific questions related to the generalizability of group-level findings to individuals. Current projects in his lab apply set theory and probability to identify sufficient conditions for emotional distress, especially among individuals with emotion dysregulation.
