Philippe Sarrazin

President

Philippe Sarrazin’s education and career are at the interfaces of science, engineering, research, and business. After studying chemistry, physics, and engineering, he obtained a Ph.D. in Materials Sciences. He devoted most of his career to technology development for innovative scientific instruments. As a scientist at NASA, he developed the technology of the X-ray diffraction (XRD) instrument inside the Curiosity Mars rover. In 2004, he founded inXitu Inc. to develop the technology at the commercial level, launching his first product in 2007 (Terra XRD/XRF, now product of Olympus). Starting in 2007, a collaboration with the Getty Conservation Institute and then Chief Scientist Dr. Chiari lead to adapting the technology to non-invasive analysis for Cultural Heritage applications. The Duetto XRD/XRF instrument was born from this effort. In parallel of eXaminArt, Dr. Sarrazin pursues his research on instruments for planetary exploration at the SETI Institute and NASA Ames Research Center, exploring new concepts such as energy dispersive Laue XRD, elemental mapping by spatially resolved XRF, high-resolution miniature Guinier XRD, etc.

Giacomo Chiari

Giacomo Chiari

CONSERVATION SCIENTIST

Giacomo Chiari studied chemistry at the University of Turin where he became a full professor in applied mineralogy. While his main initial research was in crystallography, he grew interested in scientific issues related to cultural heritage conservation. Beginning in 1968, he studied ancient earthen architecture in Iraq and developing treatment measures. In 1975 he was hired by UNESCO to propose a treatment for a 2,800-year-old decorated frieze in Peru, an assignment that led to additional UNESCO work. By the early 1980s, his professional life was divided between crystallography research and conservation work—including participating as a teacher in the ICCROM courses on earthen architecture. In 1988, funded by a major grant from Italy’s Consiglio Nazionale delle Ricerche, he devotes himself full-time to conservation-related activities, which included extensive study of Maya blue (identifying the pigment’s compounds and its geographic distribution) and working with Torraca on the analysis of ancient mortars and the development of mortars for repair. He continued his work in earthen architecture and consulted on a variety of projects in northern Italy and Rome, including analysis of Michelangelo’s Last Judgment in the Sistine Chapel.  Under the position of Chief Scientist of the Getty Conservation Institute (GCI) between 2003 and 2013, he leads a team of 18 renowned conservation scientists and fostered the development of the Duetto XRD/XRF instrument. Today, G. Chiari applies his expertise as a consultant on dedicated conservation research projects, including for the deployment of Duetto instrument and advanced user training.

Barbara Lafuente

Barbara Lafuente

Mineralogist and Database Specialist

Dr. Lafuente has over 10 years of experience applying a variety of analytical techniques for mineral identification and characterization including single crystal and powder X-ray diffraction, X-ray fluorescence, Raman and NIR spectroscopies and microprobe analysis. Barbara supports the development of in-situ planetary mineralogical instruments (XRD, XRF, Raman), and participates in Mars analog rock and soil research via mineral characterization. Her research interests also include studying clay minerals as paleoenvironmental indicators and using their F content to predict their origins.  Dr. Lafuente also specializes in scientific databases with a focus on mineralogy and astrobiology.
