I am a permanent INRIA Researcher (CR1) at the ASAP team at IRISA/INRIA Rennes. Previous to that I was a PIMS Postdoctoral Fellow at the University of Calgary, in Canada, working with Philipp Woelfel, and a Postdoctoral Fellow at LIAFA in Paris, working with Pierre Fraigniaud. I received my PhD from the University of Toronto in 2008, under the supervision of Vassos Hadzilacos.
