My research focusses on a wide range of topics in the broad area of observational cosmology and galaxy formation and evolution. One of the main aims of my research is to use observations of galaxies in many different wavelengths all the way from the optical and infra-red to millimetre, submm and radio in order to better understand how they form and evolve. This page lists some of the topics I have worked on or am currently working on as well as providing links to some useful data from these projects. The list is by no means exhaustive and will be updated as and when I find time/have interesting and exciting results to report. In the meantime, you can have a look at my list of publications
I have worked on photometric redshift predictions for a number of next generation galaxy surveys as well as comparing different photometric redshift codes on a sample of Luminous Red Galaxies from the Sloan Digital Sky Survey. Here are some links to some of those results for different surveys:
Dark Energy Survey & VISTA Hemisphere SurveyAnd here is the webpage for a meeting on photometric redshifts we organised at UCL in September 2008 if you want to access the talks given on the day:
London Photo-z MeetingA fun project I did as part of my PhD on classifying galaxies using artificial neural networks and comparing them to classifications by humans obtained as part of the Galaxy Zoo project.
Automated Galaxy ClassificationMuch of my postdoctoral research is focussed on using optical and near infra-red data to search for the rarest, brightest and most distant quasars and detailed follow-up of these objects using spectroscopy as well as millimetre, submillimetre and radio surveys.
