Dr. Andrew Davis is a chemist and polymer scientist in the Library of Congress’s Preservation Research and Testing Division. He is currently involved in work to analyze the Library’s various paper and polymer collections, with the goal of correlating fundamental polymer properties to preservation concerns in objects of cultural heritage spanning paper, adhesives, and audiovisual materials. Andrew is also involved in work to better understand the role of light, oxygen, and substrate in the fugitive nature of pigments in order to better enable public display of light-sensitive objects. He enjoys working with interns and visiting researchers, from high school students to postdocs. Andrew received his PhD in Polymer Science and Engineering at the University of Massachusetts Amherst. Prior to the Library of Congress, he has worked in the Central Research Laboratories of 3M, focused on photochemical processes affecting polymers, adhesives, and colored materials.
