I am the Geography Department's dedicated scientific software expert and IT helpdesk facilitator. I can assist with GIS enquiries (ESRI ArcGIS software as well as the open source QGIS software).  I can help with all scientific software questions, including coding in Python and other programming languages, and I can facilitate other technical needs (procurement and installation of PCs and laptops, software licensing, virtual machines, and PC repair and fault diagnosis). My role is something like that of a lab technician ... when the laboratory is a computer.

My background is in scientific software engineering, with a special expertise in climate modelling and climate data analysis. I helped to design an easy to use regional climate model and taught researchers around the world how to utilize it for climate change impacts studies. I am a Linux enthusiast and expert in Unix shell scripting.

I’m originally from the state of Kansas in the United States. I moved to Europe in 1998, first to the Czech Republic where I worked as a secondary school teacher and then to England in 2001. I’ve lived in Exeter since 2003.

I love travelling and have visited over 100 countries. I also enjoy reading, running and journaling.
