                          Bio: I am not keen to pigeonhole myself as a particular type of ecologist or conservationist, and I'd rather describe the type of research that I keep myself busy with. The interaction between pattern and process is a key interest of mine, and I explore this at various scales. Remote sensing technology is improving to the point that our ability to observe fine scale processes and the resulting broad scale patterns are dramatically improving. Combined with fieldwork, this, and other spatially explicit technologies and tools, enable me to investigate the three-way interaction between biodiversity, ecosystem function and patterns of natural resource use. In my opinion, understanding this interaction is fundamental to our ability to predict and adapt to anticipated global change. I guess you can say my work has links with systems ecology, landscape ecology, conservation biology and biogeography.
