Pier Giorgio Righetti

Pier Giorgio Righetti is a professor emeritus of chemistry. He worked primarily at the University of Milano and at the Department of Chemistry of the Politecnico di Milano in Milan, Italy. He has served as the President of the Società Italiana di Proteomica.
A special issue of Electrophoresis was published in Righetti's honor in 2006, recognizing his work developing new methods and techniques for electrophoresis. His contributions have been described as "paramount in the ability to separate biomolecules electrophoretically".
Righetti uses those techniques to study proteomes, sets of proteins that are expressed in organisms. He focuses particularly on animals and foods. Proteomics describes the proteins that can exist in a given type of cell and their interactions, form and structure. Proteins can remain intact for hundreds or even thousands of years. One of many applications of Righetti's techniques is the study of historical artifacts, analyzing minute amounts of protein left on them to learn more about their owners and the conditions under which they were used.
