I am an experienced astrophysicist and radio astronomer, based at Oxford University’s e-Research Centre (OeRC). I received my PhD from the University of Cambridge in 2012, where I was based at Trinity Hall, the Cavendish Laboratory, and the Kavli Institute for Cosmology. I have since held positions as an Associate Lecturer at the University of Sydney, Australia, and as an Excellence Fellow at the Institute for Mathematics, Astrophysics, and Particle Physics (IMAPP) at Radboud University in Nijmegen, the Netherlands. My relevant scientific publications can be found here.
My current work is focussed on the development of prototype science pipelines within the Square Kilometre Array (SKA) Science Data Processor Consortium. The SKA will be the largest radio telescope constructed to date and the largest Big Data project in the known Universe. The first phase of the project will generate 160 terabytes every second. This amounts to 5 zettabytes (5 million petabytes) of data that will be generated by the facility each year – a data rate equivalent to 5 times the estimated global internet traffic in 2015. I am also a member of the Executive committee for the POSSUM survey with the Australia Square Kilometre Array Pathfinder (ASKAP), am on the Board of the Very Large Array (VLA) Survey Science Group and co-chair of the Extragalactic Working Group, am a core member of the LOFAR telescope based in the Netherlands, and am a member of two SKA science working groups.
My PhD was in the area of observational astrophysics, specialising in the commissioning of low-frequency radio astronomy instruments for exploring cosmic magnetic fields and the evolution of galaxies. Prior to this, I studied theoretical physics at Royal Holloway, University of London. My research dissertation was on Kaluza-Klein cosmologies, and by adding extra dimensions to Einstein’s field equations, I was able to show that the extra dimensions intrinsically collapse and fuel the expansion of the 3 ordinary dimensions.
In my spare time, I am interested in understanding the fundamental forces in our Universe, such as gravitation and magnetism. My current interests include the nature of Dark energy and Dark matter, large-scale structure physics, and extragalactic magnetic fields. I am pursuing these interests using terabyte-scale datasets from modern large radio surveys and N-body simulations with GPUs.
