Our group continues to grow and we greet the latest postdoc welcome. Karim Rafie received his MSc from TU Dortmund and his DPhil from the University of Dundee. His training is in structural and chemical biology, and as a DPhil student he used this training to study the structure and mechanism of OGlcNAc transferase, including designing novel bisubstrate inhibitors. Welcome, Karim!
