I am interested in combinatorial questions in general. My thesis work deals with geometric representations of partially ordered sets, and in particular with free triangle orders (a generalization of interval and trapezoid orders). My interests lie also in applications of these ordered sets to data management, social science, biology, and mathematical psychology. I have also done work recently in graph theory and connectivity. My recent work has been in Enumerative Combinatorics and appearances and applications of number sequences to other branches of the liberal arts. A statement of my research history and interests is available here.
