Charlotte Fiskum is an Associate Professor in clinical community psychology at the Department of Psychology, Norwegian University of Science and Technology (NTNU). She completed her professional degree in Psychology and PhD in Psychology at NTNU, defending her doctoral dissertation titled 'Inconstant Hearts: Internalizing Psychopathology through the Lens of Neurovisceral Integration and Complexity' on May 15, 2019. Certified as a specialist psychologist in clinical community psychology and child and adolescent psychology by the Norwegian Psychological Association, Fiskum is trained in Eye Movement Desensitization and Reprocessing (EMDR) and somatic trauma therapy. She serves as leader of the Regulation and Health (RegHe) research group and is a member of the Personality and Health Psychology group within the department.
Fiskum's research adopts multifactorial, dynamical, and complexity-based perspectives on psychopathology, mental and physical health, with specializations in clinical psychology, trauma, body-oriented psychology, and applied psychophysiology. Her work emphasizes the body's role, context, and regulation in mental health, including autonomic regulation, cardiac variability, interoception, and psychological difficulties in children. She develops transdiagnostic interventions to bolster basic regulation and resilience in dysregulated stress activation, incorporating breathing, physical activity, visual stimuli, music, nature, and neuromodulation for preventive and low-threshold applications across systems and disorders. Current efforts target eating disorders and substance use disorders through trauma- and neuroscience-informed regulation approaches.
