  • Julian Borrill leads the Computational Cosmology Center at Lawrence Berkeley National Laboratory - a collaboration between the lab's  Physics and Computational Research Divisions to address the most computationally challenging problems in cosmology. His research is focused on deploying the most powerful supercomputers available to analyze observations of the Cosmic Microwave Background (CMB), both to determine the basic parameters of fundamental physics and cosmology and to use as a backlight to the formation and evolution of structure in the Universe. After Masters degrees in Mathematics and Political Science, Astrophysics, and Information Technology, a Doctorate in Theoretical Physics, and postdoctoral research at Imperial College London, Dartmouth College, and Berkeley Lab, he became a Staff Scientist in 1999 and Senior Staff Scientist in 2010. He is the US Computational Systems Architect for the ESA/NASA Planck satellite mission, serves on the Data Management Committee of the Simons Observatory, and was recently elected co-Spokesperson of the proposed CMB-S4 network of ground-based CMB telescopes.

  • Nationaal Instituut voor Subatomaire Fysica

    Since 2016, Juan Rojo has been Assistant Professor of Theoretical Physics at the Vrije Universiteit (VU) Amsterdam and Staff member at the Theory group of Nikhef, the Dutch National Institute for Subatomic Physics. After getting his PhD in Barcelona in 2006, he was a postdoctoral researcher in Paris, Milan and at CERN, followed by a faculty position at the University of Oxford. Juan's research interests are focused on the applications of Quantum Chromodynamics to the Large Hadron Collider (LHC) at CERN and on the exploitation of Machine Learning algorithms in High-Energy Physics.

      Do theorists dream of thought experiments?

      One of the most awkward questions that scientists must endure in family gatherings and other related social events is about what exactly we do for a living. At least my experimental colleagues can reply by explaining that they do experiments, tinker with big detectors and that they basically measure things. But a theorist? Do we spend all our time just idly sitting around and ``theorizing''? What does that even mean? And do we get paid for that? Sometimes, if I aim for a short conversation, I simply reply to these questions that ``I teach at the university'', which however often leads to the follow-up remark about what we do when we are not teaching...
