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 and classical probability. My current line of research is in an area called ``free probability.''
Here is a picture of me (while teaching a course of
introduction to free probability, in Winter Term 2011).
Some more information about me can be found in my CV (pdf file).
Here is my list of Publications. My recent papers are posted on the arXiv database.
Various links and announcements
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:
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?
During the academic year 2014-2015 I am on sabbatical leave, and I'm making a long-term visit to MAP5, the Department of Applied Mathematics of University Paris 5, in France.
