About Dr. Hobart

Sylvia Hobart is interested in connections between algebra and combinatorics, particularly the ways in which algebraic methods can be used to explore various combinatorial objects. Coherent configurations and association schemes provide one general context for this. Particular interests are theory and applications of coherent configurations, quasi-symmetric designs, 2-designs with three intersection sizes, generalized quadrangles, and directed strongly regulargraphs.
