Mary Rees

Susan Mary Rees, FRS (born Cambridge, 31 July 1953^[1]) is a British mathematician and a Professor of Mathematics at Liverpool University since 2002, specialising in research in complex dynamical systems.^[2][3]

After obtaining her BA in 1974 and MSc in 1975 at St Hugh's College, Oxford, she did research in mathematics under the direction of Bill Parry at Warwick University, obtaining a PhD in 1978. She was awarded a Whitehead Prize of the London Mathematical Society in 1988. The citation^[4]notes that, in particular,

Her most spectacular theorem^[5] has been to show that in the space of rational maps of the Riemann sphere of degree d ≥ 2 those maps that are ergodic with respect to Lebesgue measure and leave invariant an absolutely continuous probability measure form a set of positive measure.

In recent years, much of Prof Rees's work has focused on the dynamics of quadratic rational maps; i.e. rational maps of the Riemann sphere of degree two, including an extensive monograph.^[6] In 2004, she also presented an alternative proof of the Ending Laminations Conjecture of Thurston,^[7] which had been proved by Brock, Canary and Minsky shortly before.^[8]

FRS

She was elected to a Fellowship of the Royal Society in 2002.

Family

Her father David Rees is also a distinguished mathematician, who worked on Enigma in Hut 6 at Bletchley Park.
