 RESEARCH
    1) My main mathematical interests are in the fields of algebraic number theory and arithmetic algebraic geometry, with a focus on special values of p-adic and global L-functions. 
My most recent results
and research projects are joint with Cornelius Greither (Münich) and have led to the proof an Equivariant Main Conjecture in Iwasawa Theory
(
unconditionally, in char. p>0  and away from 2 and under the assumption that a certain Iwasawa mu-invariant vanishes, in char. 0.) 
By using Iwasawa co-descent, we have been able to derive the following type of results on
special values of global L-functions:
