Research Interests (summary)

The common theme in all my research is the application of techniques in pure mathematics to solve problems in particle physics. 

The first main area I study is gauge theories, and extensions of the Standard Model gauge algebra. This includes semi-simple extensions or u(1) extensions, and their classification. 

The second main area I study is the application of category theory to particle physics. Unlike e.g. group theory, category theory is not in the standard physicists curriculum. However, just because of this, it does not mean it is not the right language to frame problems in physics.
