Current projects:

One of my most ambitious projects is to solve Igusa's 1974 conjecture on exponential sums. The conjecture describes p-adic exponential sums, i.e., exponential sums modulo powers of p, uniform in p.

For a general overview on motivic integration, see the slides on motivic integration of the series of talks by F. Loeser at the 2005 Seattle algebraic geometry meeting.

Visits and honors:

During the spring term of 2014, I gave the Nachdiplom-Lectures at the ETH Zürich. I was a MSRI Research during part of the spring term 2014, Berkeley, California. I obtained an ERC Consolidator Grant with title "Motivic Mellin transforms and exponential sums through non-archimedean geometry" with ERC Grant Agreement nr. 615722 and acronym MOTMELSUM, 2014 - 2019. The CNRS of France awarded me with a "prime d'excellence" in 2011. Students of the KU Leuven nominated me for best teaching assistant in math. I was a Marie Curie Fellow at the ENS in Paris for two years from 2003 on. Further, outside of mathematics, I won a first prize on the Belgian, national contest "Axion Classics" for classical piano for adolescents in 1994.

Personal items:

Look at my favorite pianist Andrew Hill's website. Other pianists I admire are Abdullah Ibrahim, the young Vijay Iyer, and for example the classical pianist Sviatoslav Richter (see All Music Guide ).

I accompanied on the piano, in his debuting years 1992 - 1997, Filip Jordens, who is now a professional actor and singer. At that time, we performed Jacques Brel, and he still often does. We were once guests in the studios of the national Belgian Radio 1 and we were once the warming up program for Arno.
