I am the Met Office Joint-Chair at the University of Leeds, responsible for leading the Met Office Academic Partnership at Leeds and the University of Leeds Met Office Strategic (LUMOS) Research Group.I am based in the Institute for Climate and Atmospheric Science (ICAS), in the School of Earth and Environment (SEE) at the University of Leeds.

I work largely, but not exclsuively, on the tropics, particularly Africa and Asia. My research is focused on atmospheric convection and its role in weather, climate and the earth-system (particularly dust uplift). I was awarded the Royal Meteorological Society's L F Richardson prize in 2009 and the European Meteorological Society's Young Scientist Award in 2010. I am a member of the Priestley International Centre for climate and Water@Leeds.

Jan 2015 - present: Associate Professor
Apr 2014 - present: I am part funded by the National Centre for Atmospheric Science (NCAS-Weather) Feb 2013 - present: I am a water@leeds research fellow, working on atmospheric convection and precipitation. Jan 2009 - Feb 2013: I worked on convection as part of the National Centre for Atmopsheric Science (Weather). I was awarded the L F Richardson prize by the Royal Meteorological Society and the Young Scientist Award by the European Meteorological Society in 2010. July 2007 - Dec 2008: I worked on a NERC funded project analysing data from the Convective Storm Initiation Project (CSIP). I also took part in the GERB Intercomparison of Longwave and Shortwave radiation (GERBILS) project, studying dust uplift and transport in the Sahara.
July 2004 - June 2007: I was working with on the NERC funded consortium, the Convective Storm Initiation Project (CSIP).
April 2003 - June 2004: I worked on a NERC project analysing the effects of wind-shear on cirrus clouds.
October 2000 - February 2003: My PhD at Edinburgh University, ''Lake temperatures - thermal remote sensing and assimilation into a lake model'' (a copy of my thesis is available from my list of publications ).
I used to teach an introductory IDL course for postgraduates. This was to some extent based on Hugh Pumphrey's (University of Edinburgh) IDL course. Notes are available (note icons at top left that step forward/back through these). Data used in the course are available (please note that is still work in progress).Although these notes are a step-by-step introduction, I would also encourage people to look at the numerous examples in Andy Heap's (Centre for Global Atmospheric Modelling, The University of Reading) An Introduction to Using IDL in Meteorology. --- these notes contain some more sophisticated examples and also a good summary. There is also an online preview of IDL programming techniques available, as well as paper books (such as Practical IDL Programming by Liam Gumley). It's also worth looking at David Fanning's site , e.g. his slow-loops tutorial. If you do atmospheric science, Dominik Brunner's Basic IDL routines for atmospheric science are really useful. Once you think that you've really got IDL sorted you could always join the IEPA ! None of these notes really cover good and bad practise in scientific programming. For that you might want to consult Jason Lander's notes on How not to write a computer program.
