I am a postdoc at INRIA in the GEOMETRICA group. I work with Jean-Daniel.Boissonnat, with funding through the CG Learning Project.
[2013.06.18]
I am moving to the University of Groningen, where I will be a postdoc with Gert Vegter at the Bernoulli Institute.
As of today, this web page is obsolete. I will maintain a web presence here.
