I am a Professor in the
Pure Mathematics Department of the University of Waterloo.
I did my undergraduate
studies in the Mathematics Faculty of the University of Bucharest,
Romania, and the PhD Degree in the Mathematics Department of the
University of California at Berkeley, under the supervision of
Dan-Virgil Voiculescu. My research interests are in
noncommutative probability and operator algebras,
particularly their connections to combinatorics, classical
probability, and mathematical physics. My current line of research
is in an area called ``free probability.''
 
 
  Some more information about me can be
found in my CV (pdf file).
  Here is my list of
Publications.
Most of my recent papers are posted on the
arXiv database.

Here is a talk on the
Hopf algebra approach to free multiplicative convolution
and to the S-transform (pdf file) ,
given at the
American Mathematical Society Meeting
in San Diego, in January 2013.
The talk presents joint work with
Mitja Mastnak ,
and has three parts:
Here is a picture of me (while teaching a course of
introduction to free probability, in Winter Term 2011).
 
 
A. The 1-variable framework and a relation to symmetric functions.
 
 
B. Generalization to joint distributions of k-tuples.
 
 
C. A problem: boxtimes-convolution powers for k-tuples?
