My research is in the area of algebraic graph theory. I am interested in the action of groups on graphs and hypergraphs. Recently I have studied cyclic partitions of complete hypergraphs, which can be viewed as generalized self-complementary graphs. I have also studied the problem of determining under what conditions a Cayley digraph has a Hamiltonian cycle. Currently I am working on using algebraic techniques to construct hypergraph decompositions on different groups. Last summer I worked with an undergraduate summer research student on the problem of determining the metric dimension of Cayley hypergraphs and circulant graphs.
Here are the links to some conferences I have attended or will attend.
