Arne Einar Vaaler

Arne Einar Vaaler is affiliated with NTNU’s Department of Adult Psychiatry and Mental Health Care, part of the Faculty of Medicine and Health Sciences. His primary research focuses on bipolar disorders, suicide risk assessment, psychopharmacology, and the biological underpinnings of psychiatric conditions. Key projects include studies on extracellular vesicles in psychosis, genomic insights into bipolar disorder, and clinical utility of suicide crisis syndrome frameworks.

His work integrates biological psychiatry with translational research, emphasizing biomarkers (e.g., anti-neuronal antibodies, cytokines) and environmental factors (e.g., solar insolation). Collaborations span institutions globally, addressing topics like cardiometabolic health in severe mental illness and sleep patterns in psychiatric intensive care units. Recent studies highlight interdisciplinary approaches to suicide prevention and autoimmune mechanisms in psychiatric syndromes.

Publications span Nature, Nature Genetics, and Journal of Psychiatric Research, reflecting contributions to both clinical practice and fundamental science. His research group actively investigates genetic and environmental determinants of mental disorders, with a focus on improving diagnostic accuracy and treatment efficacy in acute psychiatric settings.
