Rate My Professor Rafael Bras

Rafael L. Bras is the K. Harrison Brown Family Chair and Regents' Professor in the School of Civil and Environmental Engineering within the Engineering faculty at the Georgia Institute of Technology, holding a joint appointment in the School of Earth and Atmospheric Sciences. A leading figure in hydrology, he earned his B.S. in Civil Engineering in 1972, M.S. in Civil Engineering in 1974, and Sc.D. in Water Resources and Hydrology in 1975, all from the Massachusetts Institute of Technology. A native of Puerto Rico, Bras began his academic career as an assistant professor at the University of Puerto Rico before joining MIT, where he spent 32 years as a professor in Civil and Environmental Engineering and Earth, Atmospheric, and Planetary Sciences. There, he served as Chair of the Faculty, Head of the Civil and Environmental Engineering Department, and Director of the Ralph M. Parsons Laboratory. He subsequently became Dean of the Henry Samueli School of Engineering at the University of California, Irvine, and from 2010 to 2020, he was Provost and Executive Vice President for Academic Affairs at Georgia Tech.

Bras's research centers on hydrometeorology, ecohydrology, and land-atmosphere interactions mediated by soils and vegetation, leveraging satellite observations of soil moisture and rainfall. His pioneering work encompasses uncertainty characterization in hydro-climatic processes, optimal design of observation networks, real-time data assimilation for flood and drought forecasting, soil-vegetation-atmosphere feedbacks, landscape evolution, river network dynamics, and climate change impacts from deforestation. He has published over 235 refereed journal articles and influential textbooks, including "Hydrology: An Introduction to Hydrologic Science" (1990) and "Random Functions and Hydrology" (1985, revised 1993), with highly cited papers such as "On the Extraction of Channel Networks from Digital Elevation Data" (1991, 1779 citations), "Hillslope Processes, Drainage Density, and Landscape Morphology" (1998, 810 citations), and "Precipitation Recycling" (1996, 669 citations). His contributions have profoundly influenced hydrologic modeling and prediction. Bras has received prestigious honors, including the AGU Robert E. Horton Medal (2007), MIT James R. Killian Jr. Faculty Achievement Award (2008), National Academy of Engineering election (2001), American Academy of Arts and Sciences election (2023), and ASCE Opal Award for Lifetime Achievement in Education (2025). He has advised NSF, NASA, and other bodies on critical issues.
