"Physics is not mathematics, just as mathematics is not physics. Somehow
nature chooses only a subset of the very beautiful and complex and intricate mathematics that mathematicians develop, and that precise subset is what the theoretical physicist is trying to look for." C.N. Yang according to R. Jackiw
Topics
 Nonperturbative aspects of Quantum Chromodynamics/YangMills Theories: instantons, monopoles, vortices, calorons
 QCD under extreme conditions: high temperature and/or high density and/or external magnetic field; mainly by virtue of Lattice gauge theory
 sign problem and dualizations, also in spin systems
