Rob gained his BSc (hons) in Geology from the University of Reading in 1989. This was followed by a PhD at PRIS/Department of Geography, University of Reading investigating the "sedimentology and hydrochemistry of the Chott el Djerid, Tunisia using remote sensing" which was completed in 1993. He has been a Research Assistant at Reading (1993) working on the pre-processing of AVHRR data, and then spent a summer in Iceland assisting Jukka Käyhkö on a project focused on monitoring aeolian processes. He then went on to take up a Postdoctoral Fellowship (1993-1995) and Lectureship (1995-1998) at the Department of Environmental Science, University of Stirling where his research broadened into the use of airborne remote sensing and field spectroradiometry. He was appointed Lecturer in Applied Remote Sensing at Sheffield in 1999 and in doing so returned to lecturing and researching drylands. He was subsequently promoted to Senior Lecturer in 2004, and Reader in Dryland Processes in 2007.

Research Interests

I'm interested in the global dust cycle, with particular emphasis on geomorphological and hydrological processes that occur within "dry" arid basins. As part of this, I've also worked on aspects of the remote sensing sources of dust in the climate system. As a side line, I've also worked on projects involving airborne remote sensing and field spectroscopy of a range of environments (rivers, wetlands, coasts).
As part of my Dust research, I have recently been currently part of the RCUK-funded DO4 Models programme, involving collaboration with Oxford, Imperial and UCT. The overall aim of this research was to collect the first dust source-area process data tailored to climate model grid-box resolution from targeted remote sensing and fieldwork in order to develop a new generation of model dust emission schemes. Recent work was featured on the BBC News.

Current research

My current work falls within the following three themes:

Desert Dust

  • Development and evaluation of remote sensing techniques to understand land/climate interactions, and controls on mineral aerosol emissions dryland regions

Desert dust research

Ephemeral Lakes

  • The use of global time-series of moderate resolution EO data (e.g. MODIS, SPOT-VGT, AVHRR) to determine inundation frequency and groundwater levels for large un-gauged ephemeral systems. Monitoring of the geochemistry and surface morphology of ephemeral lake systems

Ephemeral lakes research

Applied Remote Sensing

  • Use of airborne remote sensing and deployment of field spectroradiometry to constrain simple radiative transfer models for use in monitoring/evaluation of surface vegetation, sediments and soils.

Teaching

I have almost 20 years of teaching experience in a range of universities in the UK and other countries (eg Finland, Zambia and Namibia), and have taught classes of all levels and sizes. I currently teach a range of modules at the undergraduate and postgraduate level based on topics that I find to be both exciting and enabling. The major themes of my teaching are driven by my research interests and experience and encompass aspects of dryland geomorphology and the use/exploitation of a range of earth observation approaches. At all levels I encourage learning through inquiry, seek to expose students to the most up to date technological advances in geographical research, and aim to include both field and laboratory components wherever possible.

Rob teaches on a range of undergraduate and postgraduate courses including:

  • GEO108 Earth's Changing Surface
  • GEO211 Applied Remote Sensing
  • GEO232 Dryland Geomorphology
  • GEV6010 Introduction to Remote Sensing
  • GEO6804 International Development Field Class
  • GEO6807 Understanding Environmental Change

All staff also engage in personal supervision and tutoring of individual students at all three undergraduate levels in the following modules:

  • GEO163 (Information & Communication Skills for Geographers)
  • GEO263 or GEO264 (Research Design in Human or Physical Geography)
  • GEO356 (Geographical Research Project)
