Gabor Wiese works in Number Theory and Arithmetic Geometry. His methods are mostly algebraic and his approaches are often explicit and computational. A popular way of describing his research is as the mathematics grown out of the tools proving Fermat’s Last Theorem. Recently, Gabor Wiese also started to work on questions from cryptography. He held several grants from the FNR, among them two INTER grants, one with the German DFG and one with the French ANR. Gabor Wiese is very active in PhD training, having successfully supervised 8 PhD candidates at the University of Luxembourg. He was also the coordinator of the first FNR PRIDE grant in mathematics and has been involved in many others.
