He was recruited in the European Commission's Joint Research Centre (Karlsruhe, Germany) as scientific staff member in 1997 where he is Scientific Group Leader of the group "microanalyses" in the Nuclear Safety Fuel Unit. He is involved in radiation damage studies and in microstructural analyses of nuclear materials (mainly using electron microscopy). His activities are also related to the ageing of spent nuclear fuel and of waste matrices and more particularly on the effects of rare gas formation and defect interaction in nuclear materials. He currently is reviewer for scientific journals, chairman in many international conferences, Chair of the European H2020 project INSPYRE Governing Board and participates to several scientific evaluation committees.

Michael obtained his PhD from the Technical University Hamburg-Harburg and joined the University of Manchester in 1999. In 2003, he was appointed as Lecturer in Materials Performance and became a core member of the Materials Performance Centre, which focuses on nuclear materials research. Michael was appointed as Chair in Metallurgy in 2010 and has served on a number of scientific advisory boards at large scale facilities. Currently, he chairs the Scientific Advisory Council of the European Spallation Source (ESS) based in Lund, Sweden and is SAC member of UK’s Neutron and Muon Source ISIS.
Michael's research focuses on microstructure, mechanical properties and residual stresses in structural materials typically used by the nuclear, aerospace and oil & gas sector. The materials he is particularly interested in are zirconium alloys employed to encapsulate nuclear fuel, titanium alloys and nickel-base superalloys, which are applied for example in aeroengines, steels and hardfacing materials. A central aspect of his research is to develop a more physically based understanding of the development of microstructures during processing and the mechanisms that determine their performance. This is achieved by using a range of state-of-the-art analytical tools that enable characterising material in-situ and in 3D across a wide range of length-scales. This involves for example state-of-the-art electron microscopy but also the intensive use of large-scale research facilities such as synchrotrons and neutron scattering facilities.
