## Personal profile

### General

I obtained a BA in Physics and a BSc in Electrical Engineering at the Technion, Haifa, Israel and later on an MSc in Physics (relativistic field theory) and a PhD in Electrical Engineering (neural networks) at the Tel-Aviv University. In 1992 I joined the neural networks group in the physics department at Edinburgh University first as a postdoc and later on as a lecturer, working mainly on theoretical issues. In 1995 I joined the Neural Computing Research Group at Aston as a lecturer and was promoted later on to a reader (1997) and subsequently to a professor (1999). Between 2006-2012 and again between 2015-2019 I had been the Head of the Mathematics Group.
