I am a support scientist specialising in analytical chemistry and microbiology. Having worked at SAMS since 2004, my job has evolved into many different roles such as mass spectrometry, dissolved organic carbon and nitrogen, colorimetric nutrient and chlorophyll analysis for both research and commercial projects.
As a phytoplankton analyst, I have worked as part of the SAMS regulatory team monitoring potentially toxic algae in Scottish coastal waters for Food Standards Scotland since 2005. I keep my skills updated with occasional participation in the annual International Phytoplankton Intercomparison on the abundance and composition of marine phytoplankton.
I am the Radiation Protection Supervisor at SAMS, ensuring that work with ionising radiation is in accordance with current health and safety legislation. I am the point of contact for any planned radiation work in the radioisotope facility and I am responsible for the day-to-day management of the facility.
I am experienced in both coastal and offshore boat fieldwork, currently working as part of the team on ShellEye and Arctic PRIZE research trips.
