I have had a life-long interest in zoology culminating in a Bachelor of Science degree from the University of Tasmania majoring in Zoology (1999-2001) followed by a first class honours degree in foraging ecology (2002). I then worked as a research associate within the mammal browsing group before beginning a PhD with Dr Erik Wapstra in late 2004. My PhD project integrated a detailed field based study with hypothesis driven experimental studies to document the causes and consequences of social organisation within an Australia lizard species, Egernia whitii. Following completion of my PhD in October 2008, I was employed as a post-doctoral research fellow on an Australian Research Council funded project (2009-2011). The aim of this project was to examine the ecological and evolutionary significance of maternal (thermal) effects and specifically the role maternal effects play in understanding key evolutionary processes (e.g., the divergence of sex determining systems). During this project I also spent time at the University of Oxford, collaborating with Tobias Uller on a project examining colonisation dynamics in the introduced wall lizard. I moved to Oxford permanently in 2011 to begin a Marie Currie Fellowship which will allow me to explore how context dependent sexual selection influences population persistence/expansion and evolutionary diversification during colonisation.
My main area of interest lies in behavioural and evolutionary ecology. While my general interests within this area are relatively wide, the majority of my research fits within the overriding theme of examining the links between ecologically induced short-term phenotypic change (with a particular focus on behaviour), population dynamics, and long-term evolution. My previous work has examined these links within the framework of understanding the causes and consequences of social organisation, however, the overall aim of my work is to generate research that allows for a greater connect between ecological processes and evolutionary theory. The colonisation history of the wall lizard (Podarcis muralis) offers me a unique system with which to explore these broad questions as short-term phenotypic responses, as a result of the environmental and genetic context of founding populations, should have strong effects on population processes during colonisation. Therefore, understanding the impact these founding conditions have on selection within introduced populations will be of fundamental importance to identifying both the forces that promote and retard biological invasions as well as for understanding how novel phenotypic variants, in conjunction with selection based on environmental conditions, shape phenotypic diversity within natural systems.
