Dr Pierre Fleury

My general fields of research are cosmology and gravitation, within which the dark energy, backreaction, and fitting problems mostly draw my attention. My expertise covers general relativity, gravitational lensing, and the statistical theory of random processes.

Dr Marta Spinelli
During my Ph.D I worked within the Cosmology group at the Laboratoire de l’Accelerateur Lineaire (LAL) in Orsay (France). I have participated to Planck CMB data analysis from the actual building of a full temperature and polarization likelihood to the implementation of the statistical tools (ex. MCMC) needed to extract the final constraints on the standard cosmological model and its extensions in the neutrino sector. At UWC I am working with Prof. Mario Santos on HI Intensity Mapping, where techniques similar to the CMB ones can be applied to extract the cosmological information.
Dr Song Chen
My research interest lies on Radio large-scale cosmology, focusing on Radio continuum survey combined with  Cosmic Microwave Background (CMB) and other Large-Scale Structure (LSS) survey. I have been working on the CMB large scale anomalies, linear order perturbations on the radio continuum survey number counts, and  the NVSS.angular two point correlation and  radio dipole.  Besides, I am also interested in the cosmological back reaction, geometry and topology of our Universe.
Dr Imogen Whittam
 Research interests include deep continuum extragalactic radio surveys, source counts and spectral indices and what these can tell us about galaxy formation and evolution.

Areas of my research are Cosmology, Structure formation in the Universe, Intergalactic medium, Galaxy formation and Reionization – mainly, semi-analytic and analytic modeling of Cosmological Reionization and Galaxy formation.

Dr Obinna Umeh

My research interest is in the area of theoretical cosmology but gradually moving towards observational cosmology.  At the moment I am looking at how to effectively quantify non-linear corrections  on all cosmological observables.

Dr Patrice Okouma

I work at the interface between theory and modelling in cosmology.  My interests include the application of probabilistic data analysis techniques on large datasets to understand dark energy, cosmological forecasting, Growing interest in dark matter investigations and citizen science.

Dr Mattia Vaccari works on the development and science exploitation of ESA/NASA infrared space missions such as ISO, Spitzer and Herschel, and in particular on wide-area extragalactic survey projects such as ELAIS, SWIRE, SERVS, HerMES and H-ATLAS by means of multi-wavelength galaxy formation and evolution statistical studies (Number Counts, Luminosity Functions, etc).

Dr Stephen Fine

I work with large spectroscopic quasar surveys. One of my key interests is in determining the mass of the black holes that power quasars and how these black holes grow and form the population we see at the centres of massive galaxies in the local Universe.

I also work with radio continuum survey data. My interest being the link between high-redshift radio galaxies and optical quasar activity.
