Julian Borrill is a Senior Scientist in the Physics Division at Berkeley Lab, and a Senior Research Physicist at the Space Sciences Laboratory at UC Berkeley.
His current work is focused on developing the tools that will be needed to manage the huge data sets being gathered by current and future Cosmic Microwave Background missions, and to deploy them efficiently on multiple generations of high performance computing architecture.
He is the project data scientist and data management lead for CMB-S4, data management committee member and simulations lead for the Simons Observatory, and data management committee member and US data lead for LiteBIRD. For the last 20 years he has also managed the CMB community 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.
