I work as a researcher in diatoms at the Department of Natural Sciences, Amgueddfa Cymru – National Museum Wales. Diatom applications in environmental assessments of freshwaters and taxonomic, ecological and biogeographical studies of the diatom floras of Britain and Ireland, the Falkland Islands and the Himalaya are the core of my work. I am currently involved in projects on stream ecosystem restoration in England and Wales, effects of warming and pollution on freshwater ecosystems in Wales, and on lakes in the Nepalese Himalaya.
