Tiril Pedersen Gurholt

  • Researcher; PhD

Academic interests

I am a researcher at the Section for Precision Psychiatry at the Oslo University Hospital. I have extensive experience from psychiatric neuroimaging research, including structural and diffusion tensor magnetic resonance imaging (MRI), large-scale analyses, international research collaboration in the ENIGMA-consortium, and body-brain relationships in severe mental disorders and the general population.

My current research focus is on identifying the underlying mechanisms of observed comorbid links between bodily and mental disorders. Identification of these comorbid, likely reciprocal, mechanisms is important to improve patient care and develop safe and efficient personalized prevention and treatment approaches, and to improve outcomes, in conditions affecting both the body and the brain. To further our understanding of mental disorders and comorbidities, I use large-scale epidemiological population and clinical cohorts, and various phenotypes and techniques, including body and brain MRI, programming, numerical, regression, clustering, mediation, and artificial intelligence approaches. I work on clinical translation together with clinicians to make research findings clinically useful.

Students interested in pursuing a master or PhD within any of these areas of research are encouraged to contact me. 

I am a member of the Multimodal Imaging and Psychiatric Epidemiology Research Groups. I am a member of the Editorial Board of the Springer Nature Discover Mental Health Journal.
