Profile
Currently I am a Lecturer in the Maths Group at Aston.

I joined Aston in February 2004 as a post-doc under the supervision of Prof. D Saad, having spent the previous eight years in similar positions at Purdue University, Rhode Island University and Sao Paulo University.

My research expertise ranks from Statistical Mechanics, Critical Phenomena, to Learning Theory.

I am a local organiser of the 2010 one day mini-conference on the Statistical Mechanics of Glassy and Complex Systems.
