Research Profile

I am fascinated by the jigsaw of complex interactions between the evolution of mineralising organisms, ocean chemistry, atmospheric composition and Earth’s climate. The extraction of chemical signatures from fossil shells of marine micro-organisms as a tool for constraining past ocean conditions and their influence on climate, on timescales ranging from hundreds to millions of years, is fundamental to my research. Seeking innovative alternative approaches to constraining past climates has increasingly directed my research towards an understanding of the physiological response of phytoplankton to the changing carbon cycle in the past and for the future.

Teaching Profile

My teaching currently ranges from the fundamentals of chemistry, stable isotope geochemistry and the evolution of climate on long and short timescales.
