Dr Joanna L Dixon

Dr Joanna Dixon is a Senior Biogeochemist at PML. Her research is based around the microbial cycling of organic compounds; specifically DMSO and oxygenated volatile organic compounds like methanol, acetaldehyde and acetone in marine waters as part of the PML science area ‘Cycling in the Sunlit Ocean’. She has previously worked on nutrient and trace metal limitation of microbial carbon transformations from estuaries to remote ocean environments (Oceans 2025, FeeP, NERC M&FMB programme, LOIS) and aspects of carbon flow in deep-ocean bacteria (NERC BENBO programme).

Jo has a BSc (First) in Marine Chemistry from the School of Ocean Sciences, University College of North Wales (Bangor) and a PhD from the School of Environmental Science at the University of Plymouth and has worked at PML since 1998. She has published 15 ISI listed papers and a further 4 non-ISI listed but peer-reviewed papers. She has extensive experience in the analysis of carbon transformations using radio-tracers and has participated in over 15 field experiments, from the North Sea to the Atlantic and Indian Oceans. More recently she has focused her investigations within time series programmes; namely the Western Channel Observatory and Atlantic Meridional Transect. She has collaborated closely with colleagues from several universities in the UK, particularly UEA, Warwick, Plymouth and Sheffield.

Jo regularly reviews manuscripts for a range of high impact journals, is a current member of the NERC Peer Review College, and has been invited to sit on the marine moderating grant panel. She is currently supervising 2 PhD students.
