Biography

I am a postdoctoral researcher in theoretical particle physics at Syracuse University. Originally from the Detroit area, I graduated summa cum laude from Amherst College in 2006 with majors in physics, history, and mathematics, completed my PhD at Boston University in 2011, and spent two years as a postdoc at the University of Colorado Boulder. I have worked as a visitor at the Aspen Center for Physics (2013), National Taiwan Normal University/National Center for Theoretical Sciences, Taipei (2011); Lawrence Livermore National Lab (2010); CERN, the European Organization for Nuclear Research (2005), and Hope College (2003). In addition to the institutions mentioned above, I have been supported by the National Science Foundation, the Department of Energy, and the National Science Council of Taiwan.

Research

Quantum field theory plays a fundamental role in many areas of modern physics. The goal of my research is to improve our knowledge of strongly coupled quantum field theories and their potential applications to particle physics beyond the standard model. My primary tool is lattice gauge theory, a framework that enables first-principles investigations of non-perturbative phenomena. Using a broad range of lattice techniques I study strongly interacting systems that are interesting both theoretically and phenomenologically. These include models of electroweak symmetry breaking through new strong dynamics, and strongly coupled supersymmetric lattice field theories (the focus of my work at Syracuse). An essential component of this work is developing efficient numerical algorithms and optimizing them for high-performance computing environments.

An outdated but more complete description of my research has outgrown this page.
