Summary

I am the Head of the School of Mathematics and Physics, Professor of Applied Mathematics, and a member of the Nonlinear and Complex Systems Group at the University of Portsmouth.

I am a Fellow of the Institute of Mathematics and its Applications (FIMA) and a Senior Fellow of the Higher Education Academy (SFHEA). I am currently Chair of the IMA's Higher Education Committee (HEdSA) and am also an elected Council Member of the IMA.

My main area of research is non-linear dynamics, popularly known as 'chaos theory.'

I have taught a wide variety of mathematical courses across all levels.

I am happy to take calls and emails from media on a wide variety of mathematically-related topics.


Research Interests

My main area of research is nonlinear dynamics, popularly known as 'chaos theory.' Within that I am particularly concerned with the universal phenomena witnessed at the transition to chaos. This includes the spectacular quantitative universality observed in period-doubling, quasiperiodic systems, Hamiltonian systems, complex maps, and strange nonchaotic attractors. A common theme is renormalization.

PhD Research Supervision: I welcome enquiries and applications from students wishing to study a PhD with me in the area of nonlinear dynamics.

Biography

I am the Head of the School of Mathematics and Physics, and Professor of Applied Mathematics at the University of Portsmouth.

I am a Fellow of the Institute of Mathematics and its Applications (FIMA) and Chair of the IMA's Higher Educations Committee (HEdSA). I am also an elected Council Member of the IMA.

I am a former Chair of the Heads of Mathematical Sciences in the UK.

I was a member of the most recent MSOR Subject Benchmark Statement group.

Prior to comng to Portsmouth I worked at Loughborough University as a Senior Lecturer in Mathematics, and before that at Queen Mary London as a Postdoctoral Research Assistant.

I studied for both a BSc and a PhD at the University of Nottingham.

Teaching Responsibilities

I have developed and taught very many courses across all levels. Particular favourites include Mathematical Foundations, Real and Complex Analysis, Advanced Analysis, and Nonlinear Dynamics.

Media Availability

I am happy to take calls and emails from media on a wide variety of mathematically-related topics, and am aware of the need to respond to journalists in a timely manner.

Interested journalists can also contact the University's Media and Communications team for support and advice on all media engagement, including out of hours.
