Research Interests

I am a biological oceanographer who uses ocean color sensors on satellites to understand the dynamics of the microscopic phytoplankton that form the basis of the marine food webs.

My main area of focus is a type of phytoplankton called a coccolithophore. This group makes an intricate outer shell from platelets made of calcium carbonate (chalk). These platelets are often shed into the water column which changes the color of the ocean and enables us to observe them from space. In addition to being part of the foundation of most marine life, coccolithophores play an important role in the cycling carbon throughout the ocean and may also be one of the organisms that can tell us more about the impact that ocean acidification may have.

I am currently researching new ways to observe these important organisms from space, working on a better understanding of where, when and why they grow and also assessing the impact that they have on the global carbon cycle.
