Computer Science and Engineering

I am a Professor in the School of Computer Science and Engineering at UNSW.

I joined UNSW in 2012, first as an ARC DECRA Fellow and then as a Future Fellow. I obtained a PhD in Computer Science from the University of Bergen (Norway) under the supervision of Fedor V. Fomin in 2008. From 2009-2012, I held postdoctoral positions in Montpellier (France), Santiago (Chile), and Vienna (Austria).
