Claire Gervais, Professor

Claire Claire received her M.S. degree in Material Sciences and Ph.D. degree in Physical Chemistry in 2002 at the University of Rouen, France . From 2002 to 2005, she worked at the University of Bern, Switzerland as a postdoctoral fellow, focusing on the prediction of physical properties in organic molecular crystals by means of molecular modeling tools. From 2005 to 2007, she worked at the University of Georgia, USA where she developed Monte Carlo tools for studying the thermodynamic properties of membrane proteins.
She then focused her interests towards cultural heritage, with an emphasis on stone conservation, structural and chemical investigation of pigments and use of synchrotron techniques for the study of museum artefacts and ancient materials. In 2008 she became a visiting scholar at the Smithsonian Museum Conservation Institute in Washington DC, USA where she was active in setting up a scientific collaboration between the Smithsonian Institution and the synchrotron SOLEIL, France, as well as developing new methods to investigate pigment-substrate-environment interactions. It was followed in 2011 by a brief stay at the Department of Art Technology atthe Swiss Institute for Art Research.
Since March 2012, she has been granted an SNSF Professorship (section II, Physical Chemistry) by the Swiss National Science Foundation at the Bern University of the Arts, with a 65% full-time equivalent to accommodate "Mother" and "Lab" hood. Since January 2015 she has resumed her activity to a fulltime equivalent with the aim of developing a Swiss Center on Heritage and Art Sciences.

Jorge Martinez Garcia, Postdoctorate

Jorge Project: High-throughput tomography for cultural heritage.
Jorge received his Ph.D. degree in Materials Science in 2008 at the University of Trento, Italy some years after to be graduated in Physics at the University of Havana Cuba. From 2008 to 2012 he worked as a postdoctoral researcher at the Laboratories of Crystallography of the EPF Lausanne and ETH Zurich and at the group of Materials Science and Simulations of the Paul Scherrer Institute (PSI). His research activities were focused on the structure and microstructure analysis of polycrystalline materials from high resolution X-ray diffraction data and the modeling and optimization of physical properties of technologically important highly porous materials by means of numerical simulations and image processing analysis. From 2012 to 2014 he worked as senior scientist at the Lucerne University of Applied Science and Arts in the field of energy conversion systems, where he developed a mathematical model and a computer program to study the heat and mass transfer processes occurring during biomass-energy conversion and optimize key material properties. From 2015 on, he has further expanded his domaine of expertise into the fields of computer science, stochastic systems & statistical modeling as external auditor at ETH Zurich. Since January 2017, Jorge is now in charge for automatizing and developing high-throughput tomography, a necessary step towards the statistical analysis of cultural heritage collections.

Mathieu Jacot-Guillarmod, PhD. student

Mathieu Project: Study of archeological iron artefacts by tomography techniques and image processing.
Trained as a physicist at the Ecole Polytechnique Fédérale de Lausanne, Mathieu is developing algorithms and filtering/segmentation tools for getting the most out of tomography data. He analyzes the porosity in archaeological iron artefacts and its influence on the formation of corrosion products.

Giulia Moretti, PhD. student

portrait Project: Prussian blue photoreduction in paper artworks.
Trained as a conservation scientist at the University of Bologna, Giulia is working particularly on the influence of the substrate on Prussian blue photoreduction. She is synthesizing Prussian blue, preparing models of PB artefacts, fading them in controled environment and analyzing them by various techniques and with various sample preparations, from bulk to cross-sections.
