Research interests

As a postdoctoral research fellow at the National Oceanography Centre I study developmental plasticity and speciation in planktonic foraminifera. Foraminifera retain their entire developmental history in their fossil tests, allowing studies of developmental plasticity in deep time. As ambient environmental conditions are recorded in the chemical composition of the foraminifera shells it becomes possible to quantify the effects of local environmental change on morphological development and speciation.

In my PhD project I studied the effects of multivariate climate change on evolution and extinction in Pliocene - Pleistocene planktonic foraminifera lineages. The findings showed that environmental change can deflect otherwise stable allometries, and that evolutionary response is strongest to a combination of environmental factors, none of which were dominant individually. During the final stage of my PhD project I was awarded a Johanna M. Resig Research Fellowship to study origination, evolution and extinction of Middle Eocene Globigerinathekids.
