His research involves algorithms for exhaustively listing discrete structures, combinatorial Gray codes, Venn and Euler diagrams, combinatorics on words, and enumerative combinatorics.
A Gray code for numbers in a given radix is a sequence that contains each number up to a given limit exactly once, in such a way that each pair of consecutive numbers differs by one in a single digit.
