My primary research area is mathematical modeling of biological systems. I am particularly interested in ecology and evolution. My research projects focus on three major areas:

amei: Adaptive Management of Epidemiological Interventions. with Robert Gramacy, Dan Merl, and Marc Mangel.
In June 2006 I completed my Ph.D. at the University of California Santa Cruz, working with Marc Mangel in the Applied Math and Statistics Department. My dissertation is titled Mathematical Modeling of Cholera: from bacterial life histories to human epidemics. The dissertation is divided into three main chapters. First is a model of cholera in a human population that is coupled to an aquatic reservoir of cholera. The second explores a mathematical model bacterial life histories, particularly aging. Finally, I examine how different kinds of interactions between individual bacteria influence properties of V. cholerae bacterial communities.
I started my academic life as a physicist, with interests in particle physics and astrophysics. In 2002 I presented a poster entitled "Monte Carlo Studies on Proton Computed Tomography using a Silicon Strip Detector Telescope" at the IEEE MIC 2002 conference. Both my paper and poster are linked below. For list of other publications in physics see my CV .
