Here is my Curriculum Vitae
IMA Vice-President
I am the Vice-President for the Institute for Mathematics and its Applications (IMA)
responsible for Communications and Outreach and also for the 50th Birthday celebrations in 2014
More details of
my activites in maths education and public engagement are given below
CliMathNet
I am co-director of the recently established EPSRC/LWEC CliMathNet network , which has as its aim to bring together
mathematicians, climate scientists and policy makers interested in the science and the impact of climate
change.
Marie Curie ITN FIRST
Along with Victor Galaktionov and Johannes Zimmer I am a coordinator
of the Bath Node of the FIRST (Fronts and Interfaces in Science
and Technology) Marie Curie training network. See
FIRST Network for more information
about the project, workshops and positions.
Research Interests:
I am interested in the theory, application and computation of nonlinear problems (linear problems are for cissies) with special interest in problems
which arise in industry. Much of my recent work has been on the development of accurate adaptive mesh numerical methods for solving
partial differential equations, with particular application to meteorological problems. My research interests are as follows:
- Adaptive mesh methods, with applications in meteorology and climate
- Data assimilation methods, with applications in meteorology and climate
- Nonlinear elliptic and parabolic partial differential equations, especially problems with singularities.
- Non-smooth dynamical systems
- Complex systems
- Scale invariant adaptive mesh methods
- Optimal transport methods
- Numerical weather prediction
- Structural optimisation
- Power electronics
- Fourth order partial differential equations arising in geology,
structures and in nonlinear optics.
- Industrial problems, especially linked with mechanical and electrical
engineering
I also have a very strong interest in interdisciplinary
projects closely linked to applications ranging from geology
to micro-wave cooking and from digestion to folk dancing.
Education and Public Engagement Interests:
I have a passionate interest in promoting mathematics to the
general public, especially to young people. I am
a member of the
CMS Maths Promotion
Unit , Professor of Mathematics
at the Royal Institution, lecturer for
Maths Inspiration ,
coordinator of the
Bath Taps
Into Science Festival
and of the Wessex Maths Masterclasses.
If you want to have a look at Bath Taps in action here is a video .
In 2010 I was director of the exhibit in the
Royal Society Summer Exhibition called
Living in a Complex World
which gave a hands on experience of the
way that maths helps us understand the complexities in the world,
from weather forecasting and chaos to energy harvesting and from bouncing balls and sand to flocks and crowds. The website above
has lots of resources about complexity. Enjoy! If you are mad enough to want to run such an exhibition your self, then
have a look at the user guide
A user guide to running a Royal Society Summer Exhibition.
If you are interested in getting involved in public engagement work
and
would like to find out more, then have a look at my talk
I also have a strong interest in mathematics education and
serve or have served on a number of bodies that support mathematical
education. These include the MSOR Subject Centre, the MEI
Industry Ctee and the
More Maths Grads executive committee.
Until recently I was the Education Secretary of the
London Mathematical Society .
Some details of the work of the LMS Education Committee (which I
chaired) are given in the following
LMS Newsletter article
I was one of the authors of the 2011 Vorderman Report on the current state
and future of Maths Education in the UK
My philosophy for teaching is simple. Be aware of (and enjoy) your
audience and be hugely enthusiastic about your subject.
Some of my talks/articles/courses on maths education:
Communicating Mathematics
In 2001 I was awarded a National Teaching Fellowship
NTFS
and have used this to create a degree credit programme
on Communicating Maths .
Maths Communicators
is a description of the course and this is a National Coordinating Centre in Public
Engagement
Case Study . Do have a look
and email me if you would like to take this course yourself.
If you are interested in running such a course, then here is a
Guide to Good Practice
on how to do it
Non-smooth dynamics
What happens to dynamical systems when we remove the
constraint of smoothness? Lots of new and exciting
dynamics occur!! A review of these is given in my
book on

and Applications, joint with Mario di Bernardo, Alan Champneys
and Piotr Kowalczyk published by Springer.
Geometric Integration and Adaptivity:
Geometric integration is a new branch of numerical analysis
which aims to reproduce the qualitative features of the
solution of the differential equation which is being discretised.
An account of this new area is given in the following
set of notes (100 sides) which formed the basis of a short course
at SCICADE 01
