Biogeochemistry support scientist

I am a esearch technician in marine biogeochemical cycling, specialising in nutrient and carbon chemistry and marine particle transfer and decay.

Contact details:

I am a marine biogeochemist specialising in water column nutrient and dissolved oxygen chemistry and marine particle transfer. I have also worked in sediment carbon dynamics specialising in carbon burial rates, bioturbation styles and redox sensitive metals. With these skills and knowledge I help and advise on related research programs operating at SAMS.

I manage the main instrument lab, the Analytical Laboratory, at SAMS and am the Chemical Safety Advisor for the organisation and with which I share responsibility of the procedural aspects of all chemical related analyses with the Health and Safety Advisor. I am also the External Universities Field Work Coordinator.

I have extensive field going experience, having spent a month at sea every year for the past 30 years in areas including the North Atlantic, Arctic Ocean, Indian Ocean, Mediterranean Sea and Baltic Sea.
