Pablo G. Debenedetti is the Class of 1950 Professor in Engineering and Applied Science, Professor of Chemical and Biological Engineering, and vice dean of the School of Engineering and Applied Science at Princeton University. He served as chair of Princeton’s chemical engineering department between 1996 and 2004. His research interests include the thermodynamics and statistical mechanics of liquids and glasses; water and aqueous solutions; protein thermodynamics; nucleation; metastability; and the origin of biological homochirality. He is the author of one book, Metastable Liquids, and more than 200 scientific articles. Metastable Liquids was named “best scholarly book in Chemistry” by the Association of American Publishers (1997). Debenedetti’s professional honors include the National Science Foundation’s Presidential Young Investigator Award (1987), the Camille and Henry Dreyfus Teacher-Scholar Award (1989), a Guggenheim Memorial Foundation Fellowship (1991), the Professional Progress (1997) and Walker (2008) Awards from the American Institute of Chemical Engineers, the John M. Prausnitz Award in Applied Chemical Thermodynamics (2001), and the Joel Henry Hildebrand Award in the Theoretical and Experimental Chemistry of Liquids from the American Chemical Society (2008). 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 is a fellow of the American Association for the Advancement of Science.
