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

I joined Aston in September 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 ranges from Statistical Mechanics, Critical Phenomena, to Learning Theory.
