Nominator's project description

Dirk Kreimer is one of the world’s leading researchers in the field of mathematical physics. As a physicist, he is not only held in the highest esteem by his colleagues in the discipline, but also by top mathematicians with whom he regularly cooperates. At Humboldt-Universität zu Berlin, Kreimer is supposed to drive the symbiosis of mathematics and theoretical physics in Germany, focusing on fields such as quantum field theory, and helping Germany draw level with the best in the world. Kreimer is scheduled to become a member of the Department of Mathematics and the Department of Physics as well as the Director of the new Interdisciplinary Centre for Mathematical Physics.
