Portrait of Marc Hellmuth

I am professor at Leipzig University (Faculty of Mathematics and Computer Science) in Germany, where I head the Theoretical Computer Science Group. My research lies at the interface of discrete mathematics, algorithms, and computational complexity, often motivated by questions arising in the life sciences. Current topics include least common ancestors and posets in directed acyclic graphs, modular decomposition, graph theory, the mathematical analysis of biological data, and phylogenetic networks.

I live with Paula and our three children near Leipzig. When I find time, I enjoy making music, going to concerts and festivals, and sometimes simply running.
