Research Focus

My research addresses fundamental aspects of basic pharmacology, molecular pharmacology and neuropharmacology, with certain potential translational parts. The work is divided into three Work Packages each containing a number of specific projects. Work Package 1 is focused on the pharmacology of PSD95/Disc-large/ZO-1 homology (PDZ) mediated proteins-protein interaction and how these domains might represent new attractive pharmacological targets as alternatives to surface receptors. Work Package 2 will seek to explore the controversial idea that trafficking of receptors and transporters, which in many cases is strongly integrated with their pharmacology, is determined not only by protein-protein interactions, but also by yet unappreciated protein-lipid interactions that govern localization of the receptors and transporters to areas of high membrane curvature in the plasma membrane. Work Package 3 is aimed at obtaining fundamental new understanding of dopamine signaling processes in the brain. Evidently, this has broad pharmacotherapeutic perspectives given the key role of dysfunctional dopamine signaling in many brain disease including schizophrenia, bipolar disorder, ADHD, Parkinsons’ Disease and drug abuse.
