Former Members

Andreas Walker

Dr Andreas Walker joined EuPRAXIA in November 2015 and acted as the Scientific Secretary of EuPRAXIA until 2019. Before joining he worked within the LUX group at the University of Hamburg, commissioning the 200 TW ANGUS laser beamline and LUX target area; developing laser quality diagnostics; building active and passive laser beam stabilization methods; working on post plasma target diagnostics; and teaching at the University of Hamburg.

Andreas obtained his PhD from Oxford University (UK), during which time he worked on several experiments aimed towards establishing more reproducible, higher energy and more accurately measured electron beams generated by a laser-driven plasma accelerator. He completed his undergraduate research in the field of high energy physics at Heidelberg University (Germany) and at SLAC, (USA) where he studied branching fractions of semi-leptonic B meson decays within the BABAR team.

Tom Minniberger, DESY

EU Office (Finances)

Tom Minniberger has been working for the EU-Interreg Projects Baltic Sea Labour Network (2008-2011) and Science Link (2012-2014). In both projects he was  part of the management team and responsible for events, meetings and the financial administration. For the Baltic Sea Labour Network he also set up the project website .
