Julian Borrill is the Group Leader of the Computational Cosmology Center, a Senior Scientist in the Computational Research Division at Berkeley Lab, and a Senior Research Physicist at the Space Sciences Laboratory at UC Berkeley.
His current work is focused on developing and deploying the high performance computing tools that are needed to analyse the huge data sets being gathered by current Cosmic Microwave Background polarization experiments (particularly the Planck satellite, Polarbear ground-based, and EBEX balloon missions) and extending these to coming generations both of experiment and supercomputer, culminating in the recently-endorsed CMB-S4 mission which will be analysing its data a decade or more hence. For the last 15 years he has also managed the CMB community and Planck-specific HPC resources at the DOE's National Energy Research Scientific Computing Center.
Other research areas range from simulations of multi-dimensional knots of energy that might be generated in the first moments after the Big Bang to holistic performance evaluation of high performance computing systems using application-derived benchmarks.
Prior to moving to Berkeley in 1997 he held postdoctoral positions at Dartmouth College, New Hampshire and Imperial College, London. He has an M.A. in Mathematics and Political Science from the University of Cambridge, an M.Sc. in Astrophysics from the University of London, an M.Sc. in Information Technology also from the University of London, and a D.Phil. in Physics from the University of Sussex.
