F. Smith Professor of Mathematics
Steven A. Orszag, the new Percey F. Smith Professor of Mathematics, specializes in the areas of computational fluid dynamics, turbulence theory and numerical analysis.
He is also noted for his work in applied mathematics, and his research has had an impact on aeronautics, weather forecasting and the electronic chip manufacturing industry.
In the areas of computational fluid dynamics, he achieved the first successful computer simulations of three-dimensional turbulent flows. He also developed methods that provide a fundamental theory of turbulence. Another primary research interest has been the development of techniques for the simulation of electronic chip manufacturing processes, some of which have been applied extensively throughout the industry.
Orszag's accomplishments in the area of spectral methods include the introduction of fast surface harmonic transform methods for global weather forecasting and filtering techniques for shock wave problems.
Orszag is the coauthor or coeditor of nine books, including "Studies in Applied Mathematics," "Numerical Analysis of Spectral Methods," "Advanced Mathematical Methods for Scientists and Engineers," "Supercomputers and Fluid Dynamics," "Japanese Supercomputing: Architecture, Algorithms, and Applications," and "Large Eddy Simulation of Complex Engineering and Geophysical Flows." His latest book, "Partial Differential Equations for Scientists and Engineers," a collaboration with C.M. Bender, is forthcoming.
Orszag came to Yale in 1998 after teaching for 14 years at Princeton University, where he earned his Ph.D. There, he held academic posts as the Forest G. Hamrick '31 Professor of Engineering and professor of mechanical and aerospace engineering and applied computational mathematics. He earned his B.S. degree at the Massachusetts Institute of Technology and taught there for 17 years prior to joining the Princeton faculty.
For his contributions in mathematics and engineering, Orszag was awarded the G. I. Taylor Medal from the Society of Engineering Sciences in 1995 and the Otto Laeport Award from the American Physical Society in 1991. His other honors include a Guggenheim Fellowship and the American Institute of Aeronautics and Astronautics Fluids and Plasmadynamics Prize.
Orszag has served as chief editor or series editor of the Journal of Scientific Computing, the Springer Series in Computational Physics and the American Institute of Physics Series on Computational and Mathematical Physics.
