We study models and symmetries of fundamental elementary particles with emphasis on flavor physics. Flavor physics deals with the three generations of quarks and leptons and their transitions among each other. Rare decays are particularly sensitive to new phenomena beyond the Standard Model. We specialize in rare semileptonic and radiative decays of beauty quarks, and more recently charm quarks, as well as precision fits with top quark observables. Another mainstay of current research is the construction and phenomenology of a novel class of particle physics models with controlled high-energy behavior ("asymptotic safety").
