Personal profile
Biography
I am a Physical Oceanographer based at the Scottish Association for Marine Science (SAMS) and an Honorary Lecturer at UEA.
My research career began at the University of East Anglia, studying for a PhD on physical oceanography and climate science. Since then, I have focused on understanding spatial and temporal variability in the ocean, and its interactions with the wider climate system. Understanding current states of variability are crucial for predicting future changes, and therefore assessing impacts on ecosystems.
I have experience using and developing a variety of ocean models, for a variety of locations and applications, from Antarctic continental shelves to the tropical Pacific Ocean. I have developed high resolution regional ocean configurations using ROMS, GETM, Telemac3D, and NEMO (AMM15 – now used for operational forecasts at the Met Office). Ocean models are a valuable tool for investigating variability within the ocean, especially in regions where observations are limited in space and/or time.
