Profile

I'm a Senior Visiting Research Associate at the ECI; and a modeller, interested in approaches to — and implications of — all kinds of environmental modelling.

My research roots are in geomorphology: specifically, modelling soil erosion by water. This has led me to work on the impacts of changing climate and land use on erosion; self-organizing systems approaches to modelling erosion; and evaluation of erosion models.

I obtained an undergraduate degree in Environmental Sciences from Lancaster University. Then following a period in commercial computing and as a musician, I began my doctoral research at the University of Brighton, also co-publishing some of the first studies on the impacts of future climate change on erosion. In 1992, I moved to Oxford to begin work as a researcher at what was then called the Environmental Change Unit. Then in 1995 I built upon my thesis work to organise an evaluation of erosion models for the Soil Erosion Network of GCTE (Global Change and Terrestrial Ecosystems) Focus 3. This included a NATO Advanced Research Workshop in Oxford.

Perhaps the most novel research that I've done so far came out of a visit to the US Department of Agriculture's National Soil Erosion Laboratory in 1996. I'd been wondering about alternative approaches to erosion modelling. Current erosion models are complicated things, but are rather still weak at predicting where erosion will occur. Could it be that nature takes a much simpler approach? I started from the idea that erosional channels compete for runoff, just as living creatures compete for resources, and developed a self-organizing systems approach ('RillGrow') to modelling the spatial patterns of erosion by water. Initial results were very encouraging, and led to funding from the Natural Environment Research Council to develop the approach. Work on RillGrow, to enable it to be applied to larger areas, is ongoing.

Following ten years as a lecturer at Queen's University Belfast, in 2011 I returned to the ECI.
