About

I am a limnologist and palaeolimnologist by training, with a particular interest in remote lake ecosystems. I'm employed by the Environmental Change Research Centre (ECRC), one of the Department of Geography's Research Groups, and by Ensis Ltd., the ECRC's consultancy.

I graduated from the Department of Geography, UCL, in 1998 with an upper second class honours degree in Environmental Geography. I remained at UCL to do my doctoral research, receiving my Ph.D. in 2002. My doctoral thesis investigated the use of modern analogue lakes as both restoration targets and reference conditions for acidified, upland lakes in the UK, and how these modern analogues could be identified from comparisons of diatom (siliceous algae) and Cladocera (crustacean zooplankton) remains found in lakes sediments.

Since September 2001, I have worked as a research associate at UCL and Ensis on a range of projects, covering both blue skies research and applied consultancy, with a particular focus on the effects of atmospheric pollutants on remote lakes in the UK and beyond, lake acidification and eutrophication, and the future effects of climate change on these lakes. You can find out more about these projects here.

As well as my research, I am responsible for the ECRC's IT facilities and providing statistical advice to colleagues. I convene and teach on an internationally renowned course here at the ECRC on Numerical analysis of biological and environmental data analysis, and contribute to teaching within the Department of Geography to both Undergraduate and Masters level courses. I currently organise the Department's Physical Geography Lunchtime Seminars.

Quantitative methods play an important role in my research and teaching. Primarily I use the R statistical software and have written the analogue R package for analysing palaeoecological data. I am also part of the development team for the vegan package, and I maintain the Environmetrics Task View on CRAN.
