Dr. Halvorsen’s research focuses on the role of common and rare genetic variation in psychiatric disorders, with a particular concentration on Obsessive-compulsive disorder and Tourette Syndrome. He is actively involved in case/control studies of these cohorts across a wide variety of genetic data (genotype array, whole exome, whole genome), that serve the purpose of identifying specific risk variation for these disorders. He has substantial experience and retains an active interest in de novo mutation studies of these cohorts, where genetic variants present in offspring but absent from both parents are detected and assessed for their potential contribution to the disorder. He is actively interested in the downstream functional effect of risk variants identified, in particular their effect on the transcriptome of the developing nervous system.
