Professor in Geophysics

2003 PGCHET (2003, Queen's University Belfast, NI.); Ph.D. (2000, Aberystwyth University); Diplom-Geophysiker (1994, Institut für Geophysik, Christian-Albrechts-Universität Kiel, Germany)

Research interests
My research focuses on the use of applied geophysics to contribute to our understanding of the response of the world’s ice masses to past, present, and future climatic change, as well as to address related scientific problems of anthropogenic impact. Cryospheric research interests include:

  • The physical mechanisms that control ice fracturing and rifting;
  • The basal properties and processes that control fast and unstable flow of ice;
  • The physical properties of ice that control present and past ice deformation and flow;
  • Selected problems related to the glacial palaeo-record, periglacial processes, snow hydrology, contaminant dynamics in frozen ground, and geotechnical engineering and geo-hazards in glacial tills;
  • Technical developments to maximise the usefulness of geophysical methods in the cryospheric sciences, focusing particularly on multi-component seismic reflection and seismic anisotropy, electrokinetic (seismoelectric and electrical self-potential), 4-D complex electrical resistivity, and slug test methods.

I am also very interested in the application of geophysical techniques to contaminated land problems and to hydrogeological problems, and the application of state-of-the-science geophysical techniques to archaeological problems.

My research combines fieldwork, laboratory work, and forward and inverse modelling. Novel developments are sought to integrate geophysical information with other scientific approaches, e.g. through joint inversion or Bayesian modelling, fostered by extensive collaboration with other UK and international institutions.

Teaching

  • GEG268 Dissertation Preparation

    The module prepares students for their independent research dissertation through dissertation fairs, lectures and a series of tutorials focusing upon the formulation and construction of a research proposal. The module also includes three lectures which explore career opportunities for Geography graduates and skills to enhance graduate employability.

  • GEG344 Glaciology

    This module will provide you with the scientific basis to understand the physical behaviour of glacier ice at spatial scales ranging from individual ice crystals to continental-scale glaciation. The module core topics will include glacier mass balance, transformation of snow to ice, glacier hydrology, dynamics, ice crystal structure and deformation, glacier sliding, deformation of glacial sediments, glacier flow instabilities and glacier surging. We will then introduce example topics of current research interest. You will have the opportunity to work in a small group on a guided research project. The module is assessed through an individual paper critique and ¿take-home¿ examination, as well as group presentation of your research project results at a poster-based mini-conference, and as a report. The research project work will normally be assigned a group mark, however, individual student¿s marks may be moderated based on self and peer assessment.

  • GEG348 Plate Tectonics and Global Geophysics

    Over the past century our view of the dynamic earth system has shifted from continental drift to sea floor spreading and, in the 1960s and 70s, to plate tectonics. However, given greatly improved observational data and mathematical models a new revolution has been initiated in the last decade: it turns out that many familiar concepts of plate tectonics may in fact be incorrect and outdated! This includes, for instance, what we thought were established concepts of mantle plumes, hot spots, evolving subduction zones and the plates¿ driving mechanisms. Consequently, a fully revamped plate dynamics framework is currently being drawn up and integrated into a whole-earth geodynamic model. This model views the earth¿s lithosphere, deeper mantle and core-mantle boundary as coupled entities that are considerably more complex than previously thought. This has fundamentally surprising and challenging, but at the time exciting and intellectually rewarding, consequences for the dynamics of the earth¿s lithospheric plates on which we live. This module thus aims to attract open-minded students excited at the prospect of turning their view of the workings of our planet upside down, as challenged with the latest scientific hypotheses of the internal anatomy and dynamics of the earth; and indeed those of many planets in the solar system! The majority of up-to-date hypotheses and concepts will be new to the student, and are not covered by existing undergraduate textbooks. Successful completion of the module will thus require the ability and willingness to engage critically with the latest scientific literature, along with conscientious lecture attendance and continuous review of lecture materials.
