Tudor Oprea, the Visiting Professor who could not attend the inauguration of the other Visiting Professors, has now been officially welcomed at a lunch in Academicum. The day before, he also held a well-attended Sahlgrenska Academy Seminar, where he described the collaborations he plans with his hosts Huamei Forsman and Claes Dahlgren. They will continue to investigate the molecular regulatory mechanisms of so-called GPCRs, which are a group of receptors that are very common targets for modern drugs. Tudor Oprea is a Professor at the University of New Mexico’s School of Medicine in the US, and an expert in translational informatics and computational biology.
