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 www.heinrichevents.org, 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.

Teaching

  • GEC333 Ffiniau Ymchwil Daearyddol

    This module provides students with the opportunity to demonstrate their competence as a Geographer by undertaking a critical analysis of a wide variety of literature-based sources in order to develop a cogent, substantial, and persuasive argument. While the Dissertation in Geography normally focuses on the design and execution of an evidenced-based research project that assesses the capacity of students to undertake effective data analysis and interpretation, the purpose of this module is to assess the extent to which students are capable of engaging with the academic literature at the frontier of a particular part of Geography. Students select from a wide range of research frontiers in Human and Physical Geography that have been identified by the academic staff within the Department. Given that this module emphasizes student-centred learning, none of the frontiers will have been covered in other modules, although in many cases modules will have taken students up to some of these frontiers. However, to orientate students and provide them with suitable points of departure and way-stations, there will be a brief introduction to each frontier and a short list of pivotal references disseminated via Blackboard. (Note: The topic selected by you must not overlap with the subject of your Dissertation. If there is any doubt about potential overlap, this must be discussed with your Dissertation Support Group supervisor and agreed in writing.)

  • GEG101 Earth in Action

    This module introduces the three main Earth systems: the geosphere,atmosphere and biosphere. A sound understanding of the processes within each system, and of the interactions between them, forms the essential foundation for any more advanced study of physical geography. The geosphere section deals with the origin of Earth, describes the distribution of different rock types and introduces the concept of plate tectonics. The atmosphere section deals with flows of energy and moisture and their role in controlling climate over both space and time. The biosphere section deals mainly with flows of energy and nutrients and focuses on the way that life on Earth interacts with the other Earth systems.

  • GEG102 Earth's Changing Face

    Every geographer should have an understanding of the processes that form the landscape, the ways such processes have operated in the past and how they may change in the future in response to human activities and climatic change. Emphasis is given in the module to processes and how they vary across the Earth¿s surface, factors that affect Earth surface systems in different environments, and the likely consequences of human interference with natural processes. There are two main themes: 1) geomorphological and hydrological processes and their interaction with climatic change and society; and 2) natural environmental change on long and shorter timescales.

  • GEG264A Environmental Research Methods A

    The module covers research project design, data collection and some aspects of data analysis. Students are introduced to a range of laboratory and field techniques in physical geography. They gain experience in describing and interpreting results derived from laboratory techniques concerned with reconstructing the depositional history of sediments, chemical analysis of water and sediment from a variety of sources and the simulation of geomorphological processes.

  • GEGM07 Principles of Environmental Dynamics

    This module aims to explain and understand past, present and potential future changes in the Earth's climate and environment. It provides a broad approach to environmental processes and dynamics operating on land, in the oceans and in the atmosphere on a global and regional scale. Emphasis is placed on the evidence available for reconstructing past environmental dynamics, the implications for present-day processes, future predictions and likely impacts.

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.
