  • Julian Borrill

    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.

      At a friend’s birthday party this week I met a man whose opening conversational gambit – without knowing anything about my background – was a lengthy discourse on his theory of the equivalence of atomic and solar system dynamics, with electrons orbiting nuclei just as planets orbit stars... In this case, however, his immediate response was to inform me that if only I had studied the field I would understand the truth and profundity of his theory.

      Cosmic Microwave Whatnow?

      For the last 20 years, I’ve been developing pictures of the Big Bang.

      The photons created in the Big Bang have been stretched by the expansion of space and now form a faint radiation field we call the Cosmic (since it is omnipresent) Microwave (since its intensity peaks at microwave frequencies) Background (since it comes from behind all astrophysical sources). It was accidentally discovered using a huge radio telescope, and indeed about a percent of the noise you can hear between FM radio stations is this echo of the Big Bang.

      Beyond bikes, cheese, and tulips

      Juan Rojo takes us on a survey of the many enjoyable factors of living and working in the Netherlands. There's far more to the Dutch than their love of bicycles, fine cheese, tulips.

      Quo Vadis, High Energy Physics?

      High Energy Physics finds itself at a crossroads, a fact commonly recognized within the scientific community. Paradoxically, the main reason for this state of affairs is none other than the extreme success of both our theoretical framework and our experimental programs. Indeed, our current understanding of elementary particles, as encapsulated by the Standard Model, has so far been confirmed with exquisite precision by countless experiments. Even then, there are still enough urgent fundamental questions that are so far left unanswered

      Adventures and Misadventures in the Twittersphere

      I am convinced that science communications are an essential part of the scientific adventure. After all, if we investigate, how nature works at the highest energies and the smallest distances, it is important for us to tell everyone about it

      Exploring the Cosmic Frontier

      In my last post, I talked about the international Large Synoptic Survey Telescope project and the genesis of Brookhaven’s participation in it. We’re now playing a major role in developing the digital “film” that will capture the most detailed images ever of the southern sky when LSST comes online in the early 2020s. We are all really excited for that day, but as scientists typically do, we’ve already started asking, “what's next after LSST?”

      Mapping the Cosmic Frontier

      First came the talks. It was the year 2000, and scientist after scientist stood on the stage in Berkner Hall at Brookhaven National Laboratory and told us that something strange was happening to the universe. Supernova explosions from as long as seven billion years ago were not as bright as they should be. Giant sheets and filaments of dark matter were being mapped, and they did not form the structures they should.

      Life’s a beach

      You work hard as a student and as a postdoc. You stumble into a great faculty job, where your university supports you, and you get to pick what you work on. As an added sweetener, that place of employment is a short drive from some lovely beaches, has gorgeous weather (the epic floods of 2016 notwithstanding) and is incredibly affordable. Sounds great right? That’s where I’ve found myself, Australia, and it’s really not what I had on my radar five or six years ago when I was frantically hoping to get a position to keep my research adventures in high-energy physics going. But here I am. With all good jobs in high energy physics research there comes a price.
