I am a first year PhD student at the Institute of Cosmology and Gravitation which is part of the University of Portsmouth. My research is funded through the Science & Technology Facilities Council (STFC) and focuses on probes of Dark Energy using mainly data from the new Extended Baryon Oscillation Spectroscopic Survey (eBOSS) which is part of the fourth iteration of the Sloan Digital Sky Survey (SDSS) and the Dark Energy Survey (DES). I was awarded my Open BSc (Hons) degree from the Open University after gaining a Certificate of Higer Education from the University of Durham in Astronomy & Physics.

I am interested primarily in Cosmology and Astrophysics - large scale structure, dark energy, dark matter, inflation, galaxy evolution, theories of cosmology... I am especially interested in the combination of theoretical models and observational data that work to constrain each other.

Away from Physics I am a keen amateur astronomer/astrophotographer and Linux enthusiast. I am very passionate about Free & Open Source Software (FOSS) and contribute to open source software where I can (see the Links section for some great projects). Other interests include walking, reading and photography.
