I am developing new mathematical theories and computational techniques for solving graph theoretical problems, with a focus on computational complexity. My goal is to design conceptually simple, efficient, and flexible algorithms that may be useful in many different situations. I am especially interested in combinatorial problems from the biological sciences that can be expressed elegantly using graphs and tree structures. Some keywords:
Graph algorithms
Bioinformatics
Phylogenetic trees & phylogenetic networks
Computational complexity
Data structures
