Associate Director

As Associate Director I lead SAMS’ educational activity at undergraduate, masters and PhD level.

My research is related to phytoplankton and their role in marine environments. I have a particular focus on harmful algal blooms (HABs) and tools for the early warning of these events.

Contact details:

I have a background in physics but have become increasingly interested in  phytoplankton since I first started to attempt to model their growth as an undergraduate.

I now have wide interests related to marine microbes and marine biogeochemistry in terms of better understanding the factors that govern cell growth, interactions between organisms and the cycling of carbon and nutrient in marine pelagic environments.

Currently the main focus of my research is related to harmful algal blooms (HABs). These events are caused by a range of phytoplankton genera and can negatively impact human, other mammal or fish health through the production of natural biotoxins and other mechanisms. My research centers of how the physical/chemical/biological environment governs these HAB events. We are using this increased understanding to develop methods, including models and other risk assessment tools, that provide early warning of HAB events for aquaculture, regulators and the public.

Current projects

Predicting Risk and Impact of Harmful Events on the Aquaculture Sector (PRIMROSE): This project with partners in Scotland, Ireland, England, France, Spain and Portugal is developing common methodologies for better harmful algal bloom and biotoxin early warning for European aquaculture. Funded by NWE Interreg. 2017-20

Arctic Productivity in the seasonal Ice Zone (Arctic PRIZE): We are investigating the seasonally and spatially varying relationship between sea ice, water column structure, light, nutrients and phytoplankton productivity and the roles they play in structuring energy transfer to pelagic zooplankton and benthic megafauna. Funded by NERC. 2017-21

Satellite-based water quality bulletins for shellfish farms to support managememt decisions (Shelleye-2): We are evaluating the use of satellites for high biomass harmful algal bloom identification and early warning. Funded by NERC. 2017-19

Risk Assessing Harmful Algal Generated Biotoxin Events: We produce weekly HAB and biotoxin risk assessments that are made available through the web site. Funded by the European Fisheries Fund. 2017-19

Selected past projects

Minimising the risk of harm to aquaculture and human health from advective harmful algal blooms through early warning: This project developed methodologies to produce mathematical model based alerts of harmful algal blooms. Funded by NERC/BBSRC. 2015-17

CArbon/Nutrient DYnamics and FLuxes Over Shelf Systems (CANDYFLOSS): In this project we studied bacterial productivity within a large consortium of partners looking at carbon and nutrient fluxes in the Celtic sea. Funded by NERC. 2013-17

Trends in phytoplankton community structure in coastal regions of restricted exchange (RSE): This project (in collaboration with Prof. Kedong Yin from Sun Yat Sen University)  used a “Phytoplankton community index” to study the recovery of Tolo Harbour (Hong Kong) from historical anthropogenic contamination, and hence assess its environmental status. Funded by the Royal Society of Edinburgh. 2016-17

Applied Simulations and Integrated Modeling for the Understanding of Toxic and Harmful Algal Blooms (ASIMUTH): This project developed the basis of harmful algal bloom risk assessment in Europe: work that is now being furthered in a number of current SAMS projects including PRIMORSE. Funded by EU FP7. 2010-13

The harmful dinoflagellate Karenia mikimotoi in western Scottish waters: Over the period 2010-2015 we  conducted a number of Crown Estate funded projects to assess and mitigate the risk to fish farming of the harmful phytoplankter Karenia mikimotoi. Funded by The Crown Estate
