In April 2006 graduate students Tricia Muldoon and Michael Slone attended the 2nd annual Graduate Student Combinatorics Conference. It was held in at the University of Wisconsin, Madison. Tricia and Michael each gave talks. The keynote speaker was Doron Zeilberger (Rutgers).
In March 2006 Richard Ehrenborg and Carl Lee were invited to BIRS (Banff International Research Station) as part of the Convex Sets and their Applications workshop. Carl Lee gave the talk, "Multiple views of h-vectors" and Richard Ehrenborg gave the talk, "The cd-index, polytopes and Gorenstein* lattices".
Graduate student Phil Busse spent the Summer 2005 working at NSA.
