Currently I hold a Principal Research Associate position at the University of Cambridge. My main current research interest is the Square Killometre Array, which will be (once built) the largest radio telescope observing at metre and centimetre-wave wavelengths. I am the Project Engineer for the SKA Science Data Processor consortium. This means that I have the overall responsibility for the design which will however be the product of the work of a large and diverse team within the consortium. More information on the SKA SDP consortium will be available shortly on the public web-pages .
My research has previously also centred on techniques which have enabled efficient operation some of the largest and most sensitive radio telescopes in the world. For ALMA, which is the largest mm- and sub-mm wave telescope in the world, I helped develop the 183 GHz phase correction technique based on water-vapour radiometry and wrote the software which is currently used for this. This system is effectively an adaptive optics system for sub-mm wave interferometric telescopes like ALMA. More information and links to the software (available under open source GPL) are below.
Previous to that, I developed the technique of Out-Of-Focus (OOF) holography and wrote the software that is currently used for this at the Green Bank 100m (GBT) and other telescopes. The GBT is the larges single dish telescope in the world and the OOF holography system provides it with a kind of active optics system that allows it correct its surface shape during observations. More information and software (also under open-source GPL) available below.
Finally, my own astronomical research focuses on galaxy evolution and radio emission from galaxies. There is some software below available for this too!

In the brackets at the top line and near the bottom of each page on this web site there is an identifier of type “(r. XXX)” where XXX is a number. This number is a unique identifier of the revision of the web-pages, so if you’d like to reference a particular revision of these pages, you can quote this number.
