Chris Good is Professor of Mathematics at the University of Birmingham. He is the author of over 50 research articles in general topology, set-theoretic topology, topological dynamics and mathematical education.  He regularly collaborates with mathematicians around the world, including colleagues from Mexico, New Zealand, Poland and the US, as well as from Oxford, and has organised conferences in Birmingham, Oxford and Cambridge.  Chris has worked with several postdoctoral fellows and supervised a number of graduate students.  If you are interested in working with him, he would be interested in hearing from you.

Chris has a long standing interest in teaching and was awarded the first Head of School’s Excellence in Teaching Award.  He played a leading role in the development of the School’s new curriculum, championing the introduction of problem based learning and core skills.

Chris is a Fellow of the Institute of Mathematics and its Applications and Senior Fellow of the Higher Education Academy.  He has an Erdos number of 3 and an Erdos-Bacon number of 7.

Chris studied Mathematics at the Queen’s College, University of Oxford, graduating with first class honours in 1988. He completed his DPhil whilst a Junior Research Fellow at Wadham College before joining the School of Mathematics at the University of Birmingham in 1995. He was promoted to Senior Lecturer in 2001, Reader in 2012, and Professor in 2016.

Chris’s early research was in the construction of counterexamples (often using set-theoretic methods) especially around the Dowker space question and the behaviour of normality in product spaces.  He also looked at the role of the Axiom of Choice in topology and has worked extensively on generalised metric spaces, in particular g-functions and monotonicity.  More recently he has become interested in dynamical systems, in particular symbolic dynamics and the structure of invariant sets, and abstract topological dynamics.  When he is not doing mathematics, Chris loves to cook, play rugby, read, listen to music and spend time running around with his young family. He is interested in politics and the natural world.


Chris has taught over 18 different modules at all levels, ranging from Foundation Year Mathematics, through First Year Probability and Statistics, to advanced topics in pure mathematics such as General Topology, Complex Analysis and Discrete Dynamics.  He has supervised many undergraduate projects as well as undergraduate Summer research projects.  He introduced the First Year enquiry based learning modules ‘Developing Mathematical Reasoning’ (based on the influential Moore Method, with the aid of a grant from the Educational Advancement Foundation) and ‘Mathematical Modelling and Problem Solving’ and the Second Year problem solving and skills module ‘Mathematics in Industry’ (with the aid of a grant from the HE STEM Programme).

Postgraduate supervision

Chris is keen to supervise students in either set-theoretic and general topology or discrete dynamical systems and topological dynamics.  For more information about his current and past graduate students and their work please see Chris’s web page

  • Lylah Haynes, PhD (2006): Monotonizations of countable paracompactness.
  • Tom Parker, MPhil (2007): Sharkovskii's theorem and chaotic dynamical systems.
  • Andrew Barwell, PhD (2011): ω-limit sets of discrete dynamical systems.
  • Syahida binti Che Dzul-Kifli is currently looking at definitions of chaos.
  • Amna Ahmed is currently looking at the structure of continuous and order preserving maps on the rational numbers.
  • Kyriakos Papadopoulos is currently looking at characterizations of ordinals.



  • Topological dynamics: Even simple looking functions, such as the logistic or quadratic map, when iterated can exhibit complex and chaotic behaviour. This behaviour can be studied from a topological point of view.
  • Abstract dynamics: Let T be a function from the set X to itself. Abstract dynamics asks under what conditions a structure can be imposed on X with respect to which T has some meaning. For example, one might ask whether a particular abstract system T:X→X can be modelled as a continuous self-map of a compact Hausdorff space, so that there is a compact Hausdorff topology on X with respect to which T is continuous.
  • The term generalized metric is a catch all for topological spaces that share some of the structures of metric spaces. The interrelationships between these structures form a rich and varied theory.

Recently Chris has been working on:

  • The structure of ω-limit sets of tent maps and shifts of finite type using a mixture of analytic and symbolic techniques.
  • Countable dynamical systems.
  • The dynamics of included maps on hyperspaces.
  • Abstract dynamical systems modelled by compact Hausdorff spaces, separable metric spaces, the space of rational numbers and continua.
  • Coarse graining and dimensioonal reduction of dynamical systems .
