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 moving to the School of Environment. My research interests span plant ecology, spatial analysis and environmental modelling, and most of my undergraduate and graduate teaching is conducted in these areas as well. All of my research involves an empirical component, including a strong interest in dendroecology, supported by simualtion and/or statistical modelling. I am 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; I am also involved in research projects in Australia considering community structure and dynamics of species-rich shrubland ecosystems, in Western Australia, and fish population dynamics in intermittent streams in inland Victoria, using individual-based models.

Software

I have designed an Excel add-in for spatial point pattern analysis (including nearest-neighbour methods, refined nearest neighbour, Ripley's K, the neighbourhood density function, etc.) called SpPack; this software is currently being used by a number of researchers around the world and is described in a paper in Environmental Modelling & Software. This software is freely available on email request.
