Welcome

Introduction

Currently I hold a Senior Research Associate position at the University of Cambridge. This position is in large part funded by the EU FP6 ALMA Enhancement programme (see European Union FP6 ALMA Enhancement).

My current activities within the scope of this position are:

• Phase correction and calibration for the Atacama Millimetre Wave Array (ALMA) and in particular development and implementation of advanced algorithms for atmospheric phase correction using the Water Vapour Radiometers (WVRs) operating at 183 GHz.
• Remote sensing of the Earth’s atmosphere using oxygen-line temperature profilers
• Research into galaxy evolution and star-burst galaxies

Referencing these pages

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. I can provide previous revisions of the site on request.
