This thesis would not have been possible without his invaluable contribution. My sincerest appreciation is extended to the members of the dissertation committee: Professor Pierre Margot, Ph.D. (President of the committee) of the École des sciences criminelles de l'Université de Lausanne, for having passed on his passion for document examination and signature examination in particular. Professor Franco Taroni, Ph.D. (Internal expert) of the École des sciences criminelles de l'Université de Lausanne for his willingness to discuss the probabilistic assessment of evidence and for the rich literature that he published on the subject, which was a great source of inspiration for this research. I am equally grateful to Mrs. Yana Gerber, forensic document examiner from Tel Aviv, Israel and Professor Bryan Found, Ph.D., Chief Forensic Scientist of the Victoria Police Forensic Services Centre and Adjunct Professor of the Faculty of Law at the University of New South Wales, who both kindly accepted to act as external members of the dissertation committee and who provided me with remarks and questions that were a real added value to this research project. The research could not have been carried out without the help of a number of individuals and institutions. More specifically, I am indebted to: - The artists, Jean-Claude Schauenberger, Peter Bacsay, Virginia Muro, Augustin Pasquier and Jean-Marc Schwaller, for their willingness and enthusiasm to participate in this study. - The conservators-restorers of the Conservation-Restoration Section of the Bern University of Arts, in particular Karolina Soppa and Professor Sebastian Dobrusskin, Ph.D. for their vivid interest in the subject and for welcoming me within their institution for the sampling of the simulations. I also wish to thank the artists and forensic handwriting examiners who produced simulations for the study. - Raymond Marquis, Ph.D. of the École des sciences criminelles for his constant feedback and encouragement, as well as for our vivid discussions on the subject of handwriting and signature examination. The fruit of these discussions can be found on many pages of this thesis. - Alexandre Thiéry, Ph.D. for the development of the SoDe Software and his precious advice on statistical analysis. - Members of the Document Examination Group of the École des sciences criminelles, specifically Daniel Correvon and Williams Mazzella, Ph.D. - The other members of the committee of the association Think Forensic, Marie-Sylvie Martin and Durdica Hazard, for their amiable support. - All current and former teaching assistants, lecturers, scientific collaborators and professors of the École des sciences criminelles. I am very fortunate to have been surrounded by such wonderful colleagues and friends. Finally, I wish to thank my family – my parents, sisters and brother – for their invaluable support and encouragement on what has become a very enriching endeavor. to my parents, Glossary ACE-V Analysis, Comparison, Evaluation - Verification ASTM American Society for Testing and Materials GC/MS Gas Chromatography Mass Spectrometry CICP Complex Inorganic Color Pigments CO Code des Obligations FDE Forensic Document Examiner FHE Forensic Handwriting Examiner FTIR Fourier Transform Infrared Spectroscopy ICAI International Center for Art Intelligence ICOM International Council of Museums International Foundation of Art Research IFAR LC/MS Liquid Chromatography Mass Spectrometry LD/MS Laser Desorption Mass Spectrometer LR Likelihood ratio PT Proficiency Testing Pyrolysis-GC/MS Pyrolysis - Gas Chromatography Mass Spectrometry SEM Scanning Electron Microscopy UV Ultraviolet XRD X-Ray Diffraction XRF X-Ray Fluorescence
