i'm interested in lattice-point enumeration problems for polyhedra, which give rise to a rich interplay of combinatorics, geometry, and number theory, as well as a profusion of applications to numerous fields within and beyond mathematics.

reviews of and various statistics about my publications can be found at mathSciNet, zbMATH, and google scholar.

my research has been supported by the national science foundation, an sf state presidential award for professional development, and two summer grants from sf state.

using the ams' wonderfully amusing collaboration distance engine, you can find out that my erdös number is 2, my knuth number is 3, and my einstein numbers are 1 and 4 (depending on the einstein).
