Personal Statement
I am a Professor of Pure Mathematics, and my main research interests are in dynamical systems and complex analysis.

Since 2020, I hold the Chair of Pure Mathematics at the University of Liverpool that was endowed (as Chair of Mathematics) in 1882 by W. P. Sinclair and the Citizens and Shipowners of Liverpool in 1882.

I received my PhD from the University of Kiel in 2003 and have been at Liverpool since 2006.

Research Overview
My research mainly concerns the dynamics of functions of one complex variable. That is, we consider a dynamical system whose state is described by a complex number (or, more general, a point on a Riemann surface), and whose transition rule is given by an analytic function.
