Dr Gavin Tilstone is a Senior Scientific Officer at PML working in bio-optical oceanography and remote sensing. Gavin originally trained as a botanist working on physiological, genetics and ecological aspects of plant biology, specialising in marine phytoplankton. In the last ten years he has been developing marine research that directly interfaces optical oceanography and remote sensing to address key environmental issues.

Gavin’s wide-ranging research interests include: Bio-optical modelling, phytoplankton optical properties, phytoplankton photo-physiological properties, particulate and dissolved optical properties, quality assured in-situ measurements, phytoplankton production models and validation of satellite products.

Gavin has written over 40 peer reviewed research papers.
