"A Technical Study of John Singer Sargent's Portrait of Madame Pierre Gautreau"
Silvia A. Centeno
Silvia A. Centeno focuses on artists' materials and techniques and deterioration processes in paintings, photographs, and works of art on paper. She received a PhD in chemistry from Universidad Nacional de La Plata, Argentina, and started at The Met as an L. W. Frohlich Fellow to study unusual gilding techniques in Pre-Columbian metalwork. She has published and lectured on a number of topics, including pigment- and platinum-based photographic processes, daguerreotypes, heavy-metal soap deterioration in oil paintings, modern paints, early lithographic inks, and Renaissance paintings. She currently leads interdisciplinary team projects working on the elucidation of nineteenth-century photographic processes and on the deterioration of oil paintings.
