Research Interests

Currently working on Human longevity: Modelling social changes that propelled its evolution, funded by the ARC Discovery Program, under Dr Peter Kim in association with Prof Kristen Hawkes. In this project we seek to unravel what factors of human social behaviour have influenced the evolution of our life history as distinct from most other mammals. What role does grandmothering play in this context? Does male "showing off" and costly signaling play a role? To what extent (and how) are these behaviours related to one another? This is a question of evolutionary dynamics, approached from an applied mathematical perspective.

My doctoral work was on Geometric phase and periodic orbits of the equal-mass, planar three-body problem with vanishing angular momentum, supervised by Prof Holger Dullin. The thesis had two main branches: studying the symmetries of the reduced, regularised three-body problem with vanishing angular momentum, and producing a simple criterion to determine whether or not a periodic orbit of this system has vanishing geometric phase (that is, whether or not it is absolutely or relatively periodic in physical space); and a numerical survey of periodic orbits of the reduced, regularised three-body problem with vanishing angular momentum and equal masses, turning up 363 orbits, unique up to discrete symmetry, of which some are known in the literature and many are new.
