Since 2019, Giovanni Verri has been a conservation scientist in the Department of Conservation and Science. He holds a PhD in physics from the University of Ferrara, Italy, and MA in conservation of wall paintings from the Courtauld Institute of Art in London, UK. His research interests include the development and application of investigative techniques for the analysis of color. In 2007, he developed an imaging technique called visible-induced luminescence imaging, through which it is possible to map the presence of Egyptian blue, a very commonly used blue pigment in antiquity, even when otherwise invisible to the naked eye. This has led to interesting discoveries about the use of color in antiquity and beyond, including how blue was used in the skin tones of the mummy portraits at the Art Institute.
