My research focusses on marine phytoplankton, oceanic microbes that form the base of the marine food web and generate half of the oxygen we breathe.
My work is highly interdisciplinary, encompassing biological, physical and chemical oceanography and marine optics, and I use both observations and numerical modelling in my approach.
I am particularly interested in how phytoplankton growth and physiology are controlled by the physical environment. Much of my current research focusses on how light availability shapes phytoplankton biogeography and, in turn, how the community structure affects the surface ocean colour observed from satellites.
