I am a theoretical cosmologist/astrophysicist. My research tackles the origin and evolution of the largest observable structures in the Universe (if you are smaller than a few thousands light years, say a pulsar or a galaxy, you still really interest me, but you have to tell me something really cool). I am currently a Senior Research Associate at the Canadian Institute for Theoretical Astrophysics (2005-), after having spent some merry times as a Research Associate at Princeton University (2002-05). But it really all started as a student in Cambridge (1996-97) and at the Institut d’Astrophysique de Paris, where I defended my thesis in 2001.
