My mathematical interests are in combinatorics, often of an algebraic or order-theoretic nature. Some of my recent work has had to do with P-partitions, Möbius functions and edge-labellings of partially ordered sets, Schur-positivity, and relationships among skew Schur functions.

I have had the pleasure of collaborating with Sami Assaf, François Bergeron, Sara Billey, Daniel Birmajer, Emmanuel Briand, Roberto Costas, Sergi Elizalde, Juan Gil, Charlie Johnson, Stefan Leichenauer, Rosa Orellana, Christophe Reutenauer, Mercedes Rosas, Bruce Sagan, Einar Steingrímsson, Hugh Thomas, Jordan Tirrell, Ryan Ward, Mike Weiner and Stephanie van Willigenburg
