Robin Lefevre

Robin Lefevre (PhD in Materials science 2017) is currently in his second post-doc in Switzerland within Fabian von Rohr’s group. He previously spent a year in Denmark for a first postd-doc (Aarhus – Bo B Iversen) and some months in Australia. He studies different class of materials showing quantum properties. His main focus is to find compounds that show peculiar magnetic properties such as frustrated magnetism. He recently obtained the selective Forschungkredit grant allowing him to perform his research for an additional year.
All this work has been made possible after three years of PhD at the CRISMAT lab, under the supervision of Franck Gascoin, where he mastered the art of crystallography and resolving crystals structures from different techniques – including X-Ray, electron and neutron diffraction. On top of that, he surely managed to develop his knowledge on thermoelectric properties and magnetism.


Dr Clara GRYGIEL graduated in 2008 her PhD in Material Science from the Université de Caen Normandie at CRISMAT lab working on a multiscale study of the metal-insulator transition in vanadium oxide thin films. Using combination of versatile equipment spanning from the synthesis of high quality oxide films, transport properties on microbridges to high resolution X-Ray diffraction, she drawn a nice study clustering many areas of material science. Moreover I have developed skills which have been great benefits for other positions. After my PhD at CRISMAT, I moved during almost two years as post-doctoral research associate in ITN SOPRANO Network working on complex oxide thin films as mixed conductors. Back to France, I was hired in 2010 as CEA researcher at CIMAP lab in Caen working on the material behaviour under ion irradiation, specifically under dense electronic excitations, being also local contact on the international GANIL facility and scientific coordinator for a beamline dedicated to interdisciplinary physics.

Dr Florent PAWULA

I got my PhD in Physics at Université de Caen Normandie at CRISMAT lab focusing on the ruthenium oxides peculiar properties probed by Seebeck effect. Thanks to CRISMAT’s excellent environment, staff and techniques, I used solid state chemistry, crystallography and magneto-transport characterizations to study the ruthenates peculiarities. I also got the opportunity to spend 2 months at National Institute for Materials Science, Tsukuba, Japan, to study oxides and some sulfides single crystals. Being full of Normand’s cheese and cider, i.e. after graduating in 2018, I chose red wine and canelé and moved to Université de Bordeaux as a postdoc fellow at Laboratoire de Chimie des Polymères Organiques for 2 years to study the thermoelectric properties of polymers and hybrid perovskites. I am now looking forward to continue my research in Japan and enjoy again tonkatsu and sake.

Prof. Ranjith Ramadurai

Completed PhD in 2007 from Materials Research Center, Indian Institute of Science (IISc), Bangalore, in the field of ferroelectric thin films and superlattices. Later moved to CRISMAT and worked for 30 months as a post-doctoral researcher under MaCoMuFi, an EU project. I consider my stay in the Laboratoire de CRISMAT as the most fruitful stay in terms of scientific involvement and outcome. The lab environment was vibrant and lab members were very supportive and welcoming to international members. I had the freedom of hypothesizing and experimenting new ideas. I also fondly remember the scientific and non-scientific interactions I had with the lab members. Even today I cherish my intense scientific involvement during the stay at CRISMAT and the lab has played a major role in shaping my research career. The scientists and lab members have been supportive even today by extending collaborative efforts.”Later, received the Alexander Von Humboldt fellowship and worked for two years in Leibniz university of hannover. In late 2011 joined as an assistant Professor in the department of “materials science and metallurgical engineering” at IIT Hyderabad, India. Received the excellence in teaching award from IITH for 2012. Received young scientist research projects from Department of Science and Technology and Department of Atomic Energy, India in the years 2013 and 2014 respectively. In 2016 received the “MRSI-medal” for young materials researchers from MRSI, India. Current research interests are multiferroics, strain engineering in multifunctional oxide thin films and devices. Flexible, hybrid and lead free piezoelectric based energy harvesters and sensors.
