Pablo G. Debenedetti is the Class of 1950 Professor in Engineering and Applied Science, Professor of Chemical and Biological Engineering, and Dean for Research. He served as vice dean of Princeton's School of Engineering and Applied Science from 2008 to 2013 and chair of the chemical engineering department between 1996 and 2004. Debenedetti obtained his B.S. degree in chemical engineering from Buenos Aires University, Argentina (1978), and his M.S. (1981) and Ph.D. (1985) degrees, also in chemical engineering, from the Massachusetts Institute of Technology. He joined the faculty of Princeton University in 1985. He uses theoretical and computational tools to study the properties of water and aqueous systems, and their applications in areas ranging from the long-term preservation of biomolecules and pharmaceutical compounds to water desalination. Debenedetti is the author of one book, Metastable Liquids, and more than 250 scientific articles. His professional honors include a Guggenheim Memorial Foundation Fellowship (1991), the Professional Progress (1997), Walker (2008) and Institute Lecturer (2013) Awards from the American Institute of Chemical Engineers, the John M. Prausnitz Award in Applied Chemical Thermodynamics (2001), the Joel Henry Hildebrand Award in the Theoretical and Experimental Chemistry of Liquids from the American Chemical Society (2008), and the Guggenheim Medal from the Institution of Chemical Engineers (2017). He received the Distinguished Teacher Award from Princeton's School of Engineering (2008), and the President's Award for Distinguished Teaching (2008), Princeton's highest distinction for teaching. In 2008 Debenedetti was named one of 100 Chemical Engineers of the Modern Era by the American Institute of Chemical Engineers. He is a member of the National Academy of Engineering, the American Academy of Arts and Sciences, and the National Academy of Sciences, and a Fellow of the American Institute of Chemical Engineers, the American Association for the Advancement of Science and the American Physical Society.
