Omar Ghattas is the John A. and Katherine G. Jackson Chair in Computational Geosciences, professor of geological sciences and of mechanical engineering, and director of the Center for Computational Geosciences in ICES. He also holds courtesy appointments in the Departments of Computer Science, Biomedical Engineering, and in the Texas Advanced Computing Center.
He earned his Ph.D. in computational mechanics from Duke University. He has general research interests in simulation and modeling of complex mechanical, geological, and biological systems on supercomputers, with specific interest in inverse problems and associated uncertainty quantification for large-scale systems. His center’s current research is aimed at large-scale forward and inverse modeling of whole-earth, plate-boundary-resolving mantle convection; global seismic wave propagation; dynamics of polar ice sheets and their land, atmosphere, and ocean interactions; and subsurface flows, as well as the underlying computational, mathematical, and statistical techniques for making tractable the solution and uncertainty quantification of such complex forward and inverse problems on parallel supercomputers.
He received the 2003 IEEE/ACM Gordon Bell Prize for Special Accomplishment in Supercomputing, was a finalist for the 2008 and 2010 Bell Prizes, and received the 2008 TeraGrid Capability Computing Challenge award.
