James Clark is a research scientist who works within the Marine Ecosystem Modelling Group at PML. He has a Masters degree in Physics with Astrophysics from the University of York, and a PhD in Environmental Science from the University of East Anglia.

Since moving to PML in 2013, he has worked on a variety of projects, including the UK Shelf Seas Biogeochemistry Programme, which is co-funded by NERC and Defra, and a NERC funded project on the bioavailability of microplastic debris in the marine environment. As part of the latter project, he has written an offline particle tracking tool (PyLag) to help understand the movement and fate of microplastics in the marine environment.

His research interests span a range of topics, including evolutionary adaptation and acclimation in phytoplankton, marine ecology and biogeochemistry, and marine pollution.
