He is also the Theodora Shelton Pitney Professor of Environmental Studies. Professor Celia received a B.S. in Civil Engineering from Lafayette College in 1978, an M.S. in Civil Engineering from Princeton University in 1979, and a PhD from Princeton in 1983. In 1985 he joined the faculty of M.I.T., and returned to Princeton to join the Civil Engineering faculty in 1989. Professor Celia's areas of research include groundwater hydrology, ecohydrology, numerical modeling, contaminant transport simulation, and multiphase flow in porous media, with applications focused on ecohydrology in water-limited ecosystems and on large-scale geological sequestration of carbon dioxide. The carbon work is part of a large multi-disciplinary effort at Princeton known as the Carbon Mitigation Initiative. Professor Celia served for 10 years as editor of the journal Advances in Water Resources. He is a Fellow of the American Geophysical Union, recipient of the 2005 AGU Hydrologic Sciences Award, and has been named the 2008 Darcy Lecturer by the National Ground Water Association. As a contributing author for the IPCC Working Group III Special Report on Carbon Dioxide Capture and Storage, Professor shares, with many colleagues, the 2007 Nobel Peace Prize.
