# The Annual Collingwood Lecture

A generous bequest has allowed the Department to institute an annual lecture in memory of Sir Edward Collingwood FRS. The lectures are given by mathematicians of international renown and are suitable for a general audience. We welcome visitors from other departments and from outside the University.

**Professor Alison Etheridge FRS (Oxford University)**

"Some mathematical models of evolution"

23 January 2024, 1.00pm, CLC013

Alison Etheridge is Professor of Probability at the University of Oxford where she holds a joint appointment in the Departments of Mathematics and Statistics and a Fellowship at Magdalen College. She was an undergraduate at New College, and divided her graduate study between Oxford and McGill. She then held research fellowships in Oxford and Cambridge and positions in Berkeley, Edinburgh and Queen Mary University of London before returning to Oxford in 1997.

**Abstract:**
How can we explain the patterns of genetic variation in the world around us? The genetic composition of a population can be changed by natural selection, mutation, mating, and other genetic, ecological and evolutionary mechanisms. How do they interact with one another, and what was their relative importance in shaping the patterns that we see today? This question lies at the heart of theoretical population genetics.
Whereas the pioneers of the field could only observe genetic variation indirectly, by looking at traits of individuals in a population, researchers today have direct access to DNA sequences, but making sense of this wealth of data presents a major scientific challenge and mathematical models play a decisive role.
In this lecture we'll discuss some of the ways in which we can distill our understanding into workable mathematical models.

Edward Collingwood managed the family estate at Alnwick in Northumberland whilst simultaneously having a successful career as a research mathematician. He is probably known best for his work on the theory of Cluster Sets. He gave up a great deal of his time to medical administration and was, in addition, Chairman of the Council of Durham University from 1955 to his death in 1970. Collingwood College, Durham is named after him and the small research library in the Department began from the nucleus of his books, collected works and journals. He was knighted in 1962, elected to the Royal Society in 1965 and became President of the London Mathematical Society in 1969.

The first Collingwood Lecture was given in 1984 by Professor Christopher Zeeman FRS on "The discovery of perspective during the Renaissance". A list of subsequent lectures is given below.
