Dr Giliane P. ODIN is a chemist working in the BEES at UCC, as laboratory manager and post-doc. She applied chemistry to the study of cultural heritage materials, first on pigments during several internships (Louvre Museum, Paris-France, 2010; Polytechnic University of Catalonia, Barcelona-Spain, 2011), then on fossils. Her PhD, obtained in 2014 from the National Museum of Natural History of Paris (France), actually focused on the conservation of pyritized fossil specimens, by studying the origin of the alteration and developing preventive treatment. She then did a postdoctoral fellowship (University Pierre and Marie Curie, Paris-France, 2015) on the study of the internal structure in lignitized woods during wetting-drying cycles, to understand the water diffusion through fossil woods.
I am interested in the insights physical chemistry could bring to explain everyday life: from cooking to ink for 3D-printers, everything is chemistry. I am particularly involved in the investigation of physicochemical mechanisms occurring in natural and cultural heritage materials, mainly so as to preserve them. The synthesis and degradation processes are some examples of my research interests, from minerals to pigments through fossils.
Consequently, its implies a two-steps work: 1/ an experimental step, carried out with ageing or maturation chambers, to both synthesize and degrade materials; 2/ a characterization step, performed with a variety of analytical techniques, to observe the changes induced by the reactants or reaction' conditions.
I am feeling now more and more involved in what chemistry can bring to palaeontology and evolutionary questions, which is reflected by my current research, which focuses on the preservation of colors in fossils.
