As of January 2005, I am a postdoctoral researcher. Until September 2009 I mainly worked at the Département d'Informatique of Université Libre de Bruxelles, and also at Carleton University in Ottawa.
Since then I have been at Academia Sinica in Taipei, Taiwan.

I started my Ph.D. at McGill in September 2001, supervised by Godfried Toussaint
I submitted my Ph.D. thesis on January 11th and defended on March 24, 2005. The topic was Reconfigurations of Polygonal Structures. Here is an e-copy:    thesis.ps (4 Mb)    thesis.pdf (1Mb).

My M.Sc. thesis, submitted in March 2001, was on geometric estimators of location:   G_A_thesis.ps(1 Mb)    G_A_thesis.ps.gz(200 Kb)    G_A_thesis.pdf(600 Kb). For an introduction to this topic online, go here.
My undergrad major was in physics. I also took part in several mobile robotics experiments.
I've taught (and been a T.A for) this graduate course: Pattern Recognition cs644. I've also been a T.A. for: Computational Geometry cs507 , Information Structures cs610 ,
My convex hull history page (which seems to have more citations than several of my papers).
Some things I've been part of:
