RESEARCH INTERESTS I am a mathematician working in Category Theory, with special attention to categorical aspects of non-abelian algebra.
I could say that most of my research aims to answer the following questions:
Why is the category of groups so nice? Why do some categories of non-abelian structures share some nice features with the category of groups and others do not? To which extent and which aspects of group cohomology can be transferred by purely formal arguments to other non-abelian structures?
I realized some years ago that Category Theory is the way I understand mathematics, and that's the way I try to approach these questions. And new questions arise day after day...
