IMM Institute for Molecular Medicine

Research

In our research, we focus on the understanding of organismal, cellular and molecular processes in a variety of model organisms and/or cell culture. Next to the knowledge gain from this basic research, we deduce from it possible application in medicine with the vision to apply the new insights in the treatment of human disease.
