Associate Professor of Mathematics


Ph.D. in Mathematics, University of Bristol, 2001


Dr. Harrison joined the Baylor faculty in 2007. Prior to coming to Baylor served as a post-doctoral researcher at the Universität Ulm in Germany (2001-2004) and Visiting Assistant Professor at Texas A&M University (2004-2007). He is a graduate of Bristol University in the United Kingdom and is originally from Cranleigh, UK, the birth place of the famous Cambridge mathematician G.H. Hardy.  To date Dr. Harrison has supervised two Ph.D. students


Dr. Harrison's research is in mathematical physics. He is particularly interested in quantum mechanics on graphs and quantum chaos.  Topics of particular interest include anyons on graphs, zeta functions of graphs, the Dirac operator and dynamical calculations of spectral statistics.
