Andreas Jüttner is an Professor of Theoretical Physics in the Southampton High Energy Physics Group. After graduating from Friedrich-Alexander Universität Erlangen-Nürnberg he did a PhD in Computational Particle Physics at the Humboldt Universität zu Berlin. After his time as a post doc in Southampton and Mainz (Germany) he spent time at CERN in Geneva, Switzerland, as a CERN Fellow in the Theory Department. He returned to Southampton on an European Research Council Starting Grant in 2012. Andreas is currently on leave of absence on a staff position in the CERN Theory Department.
Until 05/2021 Andreas was director of the EPSRC Centre for Doctoral Training "Next Generation Computational Modelling". He is founding member of the Flavour Lattice Averaging Group (FLAG) where he is currently on the Editorial Board.
Andreas' research focuses on understanding the fundamental constituents of matter. He is particularly interested in the theory of strong interactions that describes how quarks and gluons interact to form mesons and baryons (e.g. protons, which make up the visible matter surrounding us). His research addresses the many unresolved questions still remaining such as why there is more matter than anti-matter in the universe and how the universe began. His results help understanding experimental findings coming in from the experimental facilities at e.g. the LHC at CERN in Switzerland (e.g.LHCb), KEK in Japan (BelleII), Fermilabin the US (g-2) and J-PARC in Japan (g-2).
Andreas is also interested in the development and improvement of simulations algorithms and in applying lattice techniques in other research areas. The aspects of the strong interaction Andreas is most interest in can be understood by means of numerical simulations, solving the equations of motion on high performance computers (Lattice Quantum Field Theory). To this end he is PI for a large computing time grant on DiRAC's super computers and he is also using computing resources for instance in the US or Southampton's Iridis compute cluster. He is member of the RBC/UKQCD collaboration and he is collaborating with researchers from Edinburgh, the US (Columbia University, Brookhaven National lab), Germany, Denmark and Japan (KEK).
More recently Andreas is using his expertise to address questions in Holographic Cosmology and Machine Learning.
