I completed undergraduate and Masters studies in the Departments of Geography and Plant and Microbial Sciences at the University of Canterbury, before doing a PhD at the University of Melbourne. I worked in the Dept. of Geography at King's College London for four years before returning to New Zealand and the School of Environment. My research interests lie broadly in the field of plant community and landscape ecology, with a methodological interest in spatial analysis and modelling in this context, and my undergraduate and graduate teaching is conducted in these areas. My research interests lie broadly in the field of plant community and landscape ecology, with a methodological interest in spatial analysis and modelling in this context.
My recent research has combined field-, lab- and simulation model-based approaches in the context of understanding the spatial dynamics of plant communities and the landscapes in which they occur. First, I have focused on the reciprocal effects of spatial pattern on ecological process especially in the context of understanding mechanisms of coexistence. This work has been conducted in species-rich shrublands in Western Australia and temperate forests in New Zealand. I have been PI on a Marsden-funded project considering coexistence in NZ's Nothofagus (Beech) forests using a combination of field-work (stand mapping and measurement and spatial dendrecology) and individual-based modelling. Second, I am interested in the dynamics of fire-prone landscapes and ecosystems, with a focus on prehistoric and contemporary landscapes in the southwest Pacific (New Zealand and New Caledonia) and the effects of modern land-use change on wildfire risk (Spain). In this context, I am involved in research projects with colleagues from New Zealand (Landcare Research), Australia and the USA looking at the ecological role and impacts of fire in New Zealand's prehistoric and contemporary ecosystems (Wildfire-PIRE). I am also interested in the development and application of quantitative methods in ecology - in particular, the development and application of new methods for spatial point pattern analysis and for spatial simulation. I have a joint appointment between the School of Environment and the School of Biological Sciences. During the first six months of 2012 I was based at Harvard Forest as a Charles Bullard Fellow.

I have designed an Excel add-in for spatial point pattern analysis called SpPack. This software can perform nearest-neighbour methods, refined nearest neighbour, Ripley's K, the neighbourhood density (pair correlation) function, and various Monte Carlo and goodness-of-fit procedures. SpPack is used across a range disciplines, for both research and teaching, and is described in a paper in Environmental Modelling & Software. This software is freely available on email request.
I am on the editorial board of Plant Ecology, , Perspectives in Plant Ecology, Evolution and Systematics , Geography Compass and Forests MDPI; I also regularly provide peer reviews for journals in the fields of plant ecology and ecological modelling and statistics, and for international funding agencies. I am on the council of the New Zealand Ecological Society.
