2012-2013

I recently accepted a temporary appointment with the National Science Foundation as a Program Director in the Division of Undergraduate Education (DUE). I will be working directly with the TUES (Transforming Undergraduate Education in STEM) program and the MSP (Math Science Partnerships) program as part of this change of scenery for the next year or two.

Research Interests

Graph Theory and Combinatorics is the area of my primary research interest. I have published recently on the following topics:

• Irregular Labelings of Graphs and Digraphs
• Cycle Structure in Combinatorial Structures
• Generalized Ramsey Theory
• Degree Sequences
• Saturation Number of a Graph

Here are some links that are useful for Graph Theorists:
