  • Mathematics


Algebraic number theory

My research is in the arithmetic of infinite extensions of number fields and its applications. More precisely, I am interested in:  pro-p-extensions of number fields; ramification in infinite extensions; Galois representations; iterated extensions; codes and lattices from number fields; etc.
