My principal research interests include de-glacial sea-level rise, abrupt millennial-scale climate variability, proxies for bottom current flow, dating techniques and quaternary planktonic foraminifera. In particular, my main research focus is on Heinrich Events, which were quasi-periodic, abrupt climatic anomalies that occurred during previous glacial periods, and were times when the Northern Hemisphere ice-sheet discharged large volumes of ice (hence, freshwater) into the North Atlantic. Furthering this keen interest, I co-organised a workshop in July 2012, funded by the Quaternary Research Association, entitled "Heinrich Events: Land, Ice and Ocean". The remit of the workshop was to enhance multi-disciplinary collaborations to aid our understanding of the entire ocean-climate system, using a holistic approach. Further information can be found at, and a report of the meeting has been published in the Quaternary Newsletter, Volume 128, p. 31-34

During my postdoctoral research I have worked within the RESET (RESponse of Humans to Environmental Transitions) team, and during my PhD, within RAPID. I am currently a member of the PALSEA (PALaeo SEA level) and DEGREE (DEglaciated GREEnland) research communities, and co-convened the 2013 INTIMATE EGU session.

Research Groups

  • Environmental Dynamics

    Our research group's main focus is understanding environmental variability throughout the Quaternary and the effects of future climatic change. It is centred on regions especially sensitive to environmental change (tropical, cold and wildfire-prone) and also considers interactions between climate change, human disturbance and catastrophic events.
