My Job

I am the Luis Alvarez Professor of Physics at the physics department of the University of California at Berkeley and a research scientist at Lawrence Berkeley National Laboratory My research is in the area of experimental Particle Physics. I did my undergraduate studies at the University of Hamburg in Germany and my PhD research at DESY in Hamburg on the H1 experiment at the HERA electron-proton collider. From 2001-2007 I worked on the CDF experiment at the highest energy collider in the world at the time, the Tevatron, at Fermilab in Chicago together with about 760 colleagues.

In January 2007 I joined the ATLAS experiment at Large Hadron Collider (LHC) CERN in Geneva/Switzerland. The LHC started proton-proton collisions in 2009 and took over from the Tevatron as the world's highest energy accelerator. I conduct my research at Lawrence Berkeley National Laboratory together with my colleagues from the Berkeley ATLAS group. Since March 2013 I am deputy spokesperson of the ATLAS collaboration. The picture on the left shows me in front of a part of the ATLAS experiment.

My Particle Physics Research

Particle Physics is trying to understand at a very fundamental how our Universe works. What is matter made of, what forces are there and why, what happened in between the Big Bang and now to cause the Universe to be as it is? By now we know that there are two kinds of matter, leptons and quarks, and four forces that act, the electromagnetic, the strong the weak and the gravitaional force. However, we have still many unanswered questions, e.g. cosmological data tell us that there is a lot of so-called "Dark Matter" in the Universe and the Nature of this Dark Matter is not yet understood within particle physics. Also, the fact that nowadays there is only matter and no anti-matter in the Universe is as yet unexplained within particle physics. High energy accelerators create conditions that allow us to shed light on such phenomena. At high energies new particles may be produced that could e.g. be the dark matter. The LHC currently has a center-of-mass energy 4 times higher than any previous collider. In 2015 the LHC nearly doubled the energy again, achieving a center-of-mass energy of 13 TeV.

In 2012 the LHC addressed the question whether there is a fundamental Higgs boson as was first suggested in 1964. This particle would interact with all other fundamental particles and give them mass. On July 4th 2012 the ATLAS and CMS collaborations made preliminary announcements that they see a new particle that is consistent with being a Higgs boson and ATLAS published this result end of July 2012.

The ATLAS experiment is a big enterprise: about 3000 scientists and many engineers and technicians are currently involved in operating the experiment and analyzing it's data. The opportunities for making a new discovery are great which is why so many scientists work on ATLAS and its rival experiment CMS. The experiments are also so complex that it takes so many physicists plus many many technicians and engineers to first construct and now operate these detectors.
