I focus on designing parameterized algorithms for hard problems in bioinformatics. Application areas include RNA bioinformatics and evolution, with my current post-doctoral project being about the comparison of phylogenetic networks.
My research interests more largely include graph theory, graph algorithms, general bioinformatics and quantum computing (see CV).
