Currently, I'm a PhD student at the Max Planck Institute for Informatics, my advisor is Karl Bringmann. I am interested in designing (faster) algorithms and matching conditional lower bounds for problems that are solvable in polynomial time, and those that are (probably) not. In particular, I work on problems in the area of combinatorial pattern matching and on Knapsack-type problems. Further, I am interested in the (parametrized) counting complexity of problems such as counting how often a graph appears in another graph as an (induced) subgraph.
