Current research interests focus on combinatorial structures such as
designs, hypergraphs and codes and their properties and as well as related
areas of application. I am particularly interested in algorithmic and
computational issues related to these structures.
Recent investigations have utilized probabilistic methods and I expect
to continue to explore this approach especially as it relates to
random structures and their properties.
