I am a theoretical and mathematical physicist. My primary research interests are classical and quantum gravity, noncommutative geometry, gauge theory, and high energy physics. My current research involves using the representation of three- and four-manifolds as branched covers to construct physical models for the gravitational field. I have also worked on exotic smooth structures and have a particular interest in loop quantum gravity. On this page you will find links to my research projects, some teaching resources, and other interesting things related to physics, astronomy, and non-science related topics.
