Biography

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).

Research Intrest

Microbial cycling of organic compounds, oxygenated volatile organic compounds like methanol, acetaldehyde and acetone in marine waters.
