Dr Victoria Mann is a Research Fellow in the School of Metallurgy & Materials and is also the CrEAM Network Coordinator.

Biography

Vicky Mann graduated in 1996 with a BEng(Hons) in Materials Science at the University of Birmingham. She worked in industry for a year in a copper foundry before returning to study a MPhil (qualified 1999) and subsequently a PhD on the processing of rare-earth/transition metal magnetic alloys and powders (qualified 2002).

After becoming a research associate Dr Mann was the coordinator for the MedMag Network, an EPSRC project to initiate and exploit the use of magnets in medicine. She was then employed as a research fellow between 2003 and 2012 in the Hydrogen Materials Group at the University of Birmingham studying the challenges associated with the production, storage, distribution and utilisation of hydrogen for use as an energy vector. During her time in the Hydrogen Materials Groups Dr Mann was involved in the design of three new hydrogen labs as well as the selection, specification and installation of over 30 pieces of equipment.

Dr Mann returned to the Magnetic Materials Group in 2013 to work on the multi-disciplinary EU funded research project REMANENCE developing the hydrogen recycling processing route to recover Nd-Fe-B from computer hard disk drives and reprocess the material into sintered magnets. Since the completion of the REMANENCE project she has been involved with the setting up of the BCSECM (Birmingham Centre for Strategic Elements and Critical Materials) and is now the coordinator for the CrEAM (Critical Elements and Materials) Network.
