Mood and Anxiety Disorder Treatment & Research Program bio

Dr. Lohoff’s research interest is in the genetics and pharmacogenetics of mood and anxiety disorders. Dr. Lohoff has expertise in the identification of molecular genetic targets of complex psychiatric diseases. His focus is on human genetic association studies with translational aspects using in vivo/vitro systems and animal models to verify identified risk alleles. This includes current investigation of presynaptic vesicular monoamine transporters as targets for novel drug development. Dr. Lohoff is also leading a clinical psychiatric pharmacogenomics program investigating new biomarkers that predict treatment outcome in mood and anxiety disorders.
