A main focus of my group is development of ligands with novel pharmacological profiles at G protein-coupled receptors. Another interest is to understand ligand-receptor interactions, subtype selectivity, activation mechanisms and signaling pathways at the molecular/mechanistic level.

Another focus area is orphan receptors for which the endogenous ligands remains to be identified. We have identified putative endogenous and/or surrogate ligands for a range of orphan receptors including GPRC6A, GPR139, GPR15 and GPR132.

Finally, the group work with clinicians and geneticists with the aim of understand molecular mechanisms of disease and improve treatments via personalized medicine.

1. Identified putative endogenous ligands for orphan receptors
2. Delineated mechanisms of allosteric modulation and receptor internalization
3. Coupled genetic variants in humans with receptor function
