Leader of the group
Pierre received a Micro-engineering degree (Ingénieur en Microtechnique) from the Swiss Federal Institute of Technology of Lausanne (EPFL) in 1997. After a few years of industrial experience he started a PhD thesis working at the Paul Scherrer Institut and obtained his degree from the Swiss Federal Institute of Technology of Zürich (ETHZ) in 2009. Since then, he has been leading the activity of neutron imaging of fuel cells and other electrochemical systems at PSI. In 2015, he performed a 6 research stay at CEA in Grenoble (France) on the topic of small angle neutron scattering of operating fuel cells.
Jongmin is currently working on understanding ice formation in operating fuel cells as well as developing neutron grating interferometry (nGI) for the detection of gas diffusion layer (GDL) damage. He received PhD degree in Mechanical Engineering from University of Toronto in 2017, focusing on the effect of water distribution in GDLs on fuel cell performance through synchrotron imaging. Prior to join NRES group, he was a postdoctoral fellow in CEA (Grenoble, France) where he performed many in situ fuel cell experiments at large scale facilities including ILL, ESRF, and NIST.
Dirk received his Mechanical Engineering degree from the University of Applied Sciences, Cologne (Germany) in 2009. After two years as a scientific assistant in Cologne he moved to Ingolstadt to work for Audi. Then in February 2015 he moved back to his roots in southern Germany and joined PSI. As an Engineer in the Group – Neutron Radiography of electrochemical systems he is designing test fuel cells, test-benches, software, and many more trying to support the group members as good as possible.
Wenmei recieved her Masters degree in Materials Science and Engineering from Tsinghua University (China) in 2017, where she did her master thesis on thermal energy harvesting using metamaterials. After that she worked on oxygen semi-permeation membrane as a scientific assistant in Stuttgart until she joined PSI in 2019 for her doctoral studies. Wenmei works on understanding the behavior of super-cooled water in complex porous materials and develop synthetic strategies and engineered solutions to prevent the propagation of freezing in fuel cells.
Mateusz graduated from Lodz University of Technology with major in Power Engineering (Mechanical dept.) in 2016. During his studies he worked for Alstom Power as plant designer assistant and upon completing his contract he decided to broaden his experience by joining PSI Nuclear Energy and Safety division as scientific assistant. Seeing future in making renewable energies sustainable, Mateusz joined research on PEM water electrolysis using neutron imaging.
Ricardo has a degree in engineering physics from ITESM (Mexico), where he worked on RX-NDT for aeronautical materials and in micro and nano-fabrication techniques at MTL - MIT. Afterwards, he received two Master degrees in Applied Physics and Material Science from the University of Rennes 1 and the University of Montpellier, respectively. During this time, he worked on Energy Selective neutron imaging for PEFC and Li-ion batteries at PSI, which greatly developed his interest in energy storage and conversion systems. Ricardo continues his professional development as a doctoral student at PSI, where he works on the understanding of transport limiting mechanisms for Li-ion battery materials using energy selective neutron imaging.
