Research Interests: Geometric Topology, Sheaf theory.

Dr. Snyder received his Ph.D. in Mathematics from University of Tennessee in 1988. Dr. Snyder is currently active in the areas of computation of topological invariants of geometric structures (e.g., molecules) based on discrete information (mathematics and molecular biology), analysis of learning styles using Boolean constructs (mathematics and psychology), and the use of sound to distinguish data structures.
