As with so many ecologists it is hard to tell when the child with a net and jam-jar dabbling in a pond turned into the researcher with a net and a white tray dabbling in multivariate statistics. I am by training a zoologist (University of Bristol, 1980), the great good fortune of a doctorate from John Lawton’s lab at York, (1985) and five years at Edinburgh University’s Department of Forestry and Natural Resources before joining Northumbria University. And like so many academics, the occasional diversion as shop assistant, civil servant and Punch and Judy man.

My research focuses on three areas (1) ponds, wetlands and their biodiversity, in particular changes over time and space, plus the role of ponds in the carbon cycle; (2) skateboarding culture and the use of cities by young people and (3) pedagogy and students' university experience, primarily the impacts of lad culture.

There are unifying themes which probably reflect the deeper, personal interests that motivate any researcher. For example the ecology of ponds and how youngsters play in cityscapes both have strong elements of fragmented, contingent time and space. Environments change. It is probably not a fluke that the title of one of my pond papers promises the "element of chance" in the distribtuion of pondlife, whilst a skateboard paper spotlights the "accidental youth club". My research repeatedly tunes into that delicate border between a deterministic world and the times and places that do not fit.

Recent pond work has focused on quantifying the importance of ponds in carbon dynamics. Ponds are ubiquitous across the landscapes of Planet Earth, found on every continent, from the heart of ancient deserts to tiny oceanic islands, but have been overlooked. Turns out that typical temperate lowland ponds can bury organic carbon rapidly, and have high levels stored in their sediemtns compared to surrounding grassland and forest. However some can be sources of methane and carbon dioxide, or switch back and forth between being a sink or source within days. Ponds are easy to creeate and fit into so many landscapes. they could be a significant help to mop up carbon, but we're not yet sure precisely which types of ponds work best.
