Dr. Kuo has directed undergraduate research projects and currently serves as a cocoordinator for the M.S. in Applied Math program.

Dr. Charles Lamb joined the department in 2012 after doing his Ph.D. work in spatially discrete differential equations at the University of Kansas. His research interests include the modeling, analysis, and the numerical analysis of both spatially discrete problems and biological phenomena.

Dr. John Lattanzio received his B.S.Ed. in Mathematics Education in 1990 from Indiana University of Pennsylvania. He received his Ph.D. degree from the University of Pittsburgh in 2001. His dissertation focused on the theory of graph coloring, in particular, the properties of critical vertices and critical edges in graphs. Dr. Lattanzio was promoted to the rank of Professor in 2012.

Dr. Lattanzio focuses his research efforts in finding solutions to unsolved problems in **graph theory**. He has devoted a significant amount of time working on the Erdős-Lovász vertex double-critical conjecture which has remained unsolved since 1968. He has published five research articles and three *Mathematica* computer programs. Additionally, he has given several presentations of his research at the international, national, regional, state, and local levels. His current research interests involve applying algebraic methods to graphs. In particular, he studies how the group of automorphisms of a graph acts on the set of all partitions determined by a proper coloring of the vertices of the graph.
