The Center for Multiscale Theory and Computation (CMTC) was founded in spring 2013 as an association of work groups from chemistry, physics and related research areas. All these groups are working on the theoretical description and computer simulation of molecular, macromolecular and biomolecular systems as well as condensed matter. With this pooling of know-how, a closer cooperation between the theory groups as well as between theoretical and experimental groups is achieved. As a result, the position of Münster on the map of theoretical research is stressed and a contact point for interested students and junior research groups as well as cooperation partners is created.
