Research

My main focus is on understanding the evolutionary dynamics of a variety of biological proceses by developing a mathematical description mainly utilising evolutionary game theory in conjunction with stochastic processes.

Evolution is the common theme linking everything in biology from individual alleles to language. The abstracted general principles of evolution can be represented by precise mathematical equations. Simplicity is invoked by making use of the minimum factors that matter. However all this is done to reduce the complexity of the natural world and thus results in a loss of information which may or may not be significant. How can we take this complexity into account if we aim at retrieving simple tractable explanations of biological principles? I am interested in tackling this question and to do so I use tools such as evolutionary game theory, population genetics, dynamical systems theory etc. . Besides making use of these tools I am actively engaged in expanding their foundations so that they can be applied to specific examples. Such a general view has helped me diversify into different fields ranging from population genetics, eco-evolutionary dynamics, information theory to genetic engineering. Here at Massey I aim to make use of these skills to contribute to the theory of the evolution of multicellularity as well as possibly provide a theoretical basis for other ongoing experimental research.
