I am a Quaternary Scientist, Geomorphologist and Hydrogeologist who focusses on the dynamics of Dryland Environments. 

Within Dryland Environmental research my interests span timescales from recent decades back to 100s of thousands of years, and addresses two broad themes:
1) The sediment moisture component of the hydrological cycle (quality and quantity) 
2) Landscape dynamics in Drylands using geoproxies (such as sand dunes). 


These are my current research projects, divided by my two research themes. 

Which includes: 
  • Palaeomoisture records in sandy deserts (a review of the proxy) 
  • Rainfall in the Desert Sand of Namibia (Stampriet Basin study) 


Which includes 
  • Attempting rapid age assessment of dune sediments in the Namib Sand Sea using a portable luminescence reader 
See also past research projects.


1) Quaternary climate change

Here are some thoughts on the puzzle of Last Glacial Maximum in southern Africa. I'm interested to hear any views on this and the on ways forward...

2) Current-day dryland groundwater 
In the (only very slightly soggy) sands of the Kalahari, some locations contain a lot of nitrate. Is this sheep pee or has it been biologically produced by vegetation that behaves in transient manner across landscapes over decades?  Read here for what I and Mike Edmunds think, and you decide

On 29th October I am attending The Nitrogen Cycle and the Anthropocene at BSG, Keyworth, Nottingham, where I will present a poster on this. 


I currently teach these courses at the University of Manchester. 

I also contribute to teaching on the MSc in Water Science Policy and Management at the University of Oxford. 

I have lectured for the Earth Systems Dynamics Course on the Geography BA programme in the School of Geography and the Environment at the University of Oxford. 
I have also taught tutorials across a range of Physical Geography, Environmental Geography and Geographical Techniques for the  Geography BA programme at St John's College, Keble College, Christchurch College, Worcester College and St Hilda's at the University of Oxford. 


1) Recent conferences 

2) Latest publication 


Catch members of @QEG introducing the Ice Age to members of the public at the Manchester Science Festival next week, 11am-1pm Monday 27th to Friday 31st October. 

I prepared a FACT SHEET for visitors to the Kalahari Anib Lodge, Gondwana Collection Namibia (to whom we are very grateful for granting us permission to sample dunes). Dr Chris Brown, chairman of the environmental committee has developed this into a tourist infomation board.
