I studied for my first degree at the University of Wales, Aberystwyth between 1990 and 1993, and for my MSc at the University of Oxford in 1994. I completed my PhD on the schooling behaviour of freshwater fish at the University of St. Andrews in 1997 where I was supervised by Professor Anne Magurran (http://www.st-andrews.ac.uk/~guppy/). During this time my field work was based in Trinidad and Tobago, and at the CEH River Laboratory, Dorset (http://www.ceh.ac.uk/sections/re/re.html )

In 1998 I began working as a NERC Research Fellow based at the University of Glasgow (http://www.gla.ac.uk/ibls/DEEB/) and the Fisheries Research Services, Freshwater Laboratory, Pitlochry (http://www.marlab.ac.uk/FRS.Web/default.aspx). I joined Cardiff University in 2000 when I was awarded an extension to my NERC fellowship and was simultaneously appointed as lecturer in animal ecology. In 2007 I was appointed Senior Lecturer.

My research focuses on the following themes in aquatic ecology, which link fundamental research to practical problems faced by conservation biologists and managers. The work uses a range of behavioural and ecological tools and investigates the interactions between individual behaviour and population processes essential for understanding and conserving natural biodiversity.
