About the PNAS Member Editor
Name Sethian, James A.
Location University of California, Berkeley
Primary Field Applied Mathematical Sciences
Secondary Field Engineering Sciences
 Election Citation
Sethian has developed numerous, highly original and widely used algorithms for front and wave propagation, combustion, etching and deposition processes, inverse problems, medical imaging, control, multiple arrivals and seismic analysis in geo-physics, computer graphics, industrial processes such as inkjetting, and printing, including (with Osher) the famous level set algorithm.
 Research Interests
Sethian works in the area of computational physics, combining mathematical formulations and efficient algorithms to model a host of scientific and engineering problems, particularly those involving propagating interfaces. Examples include methods to model multiphase multiphysics problems, such as in fluid mechanics, combustion, and industrial foams, algorithms to optimize engineering processes, such as the manufacture of semiconductors, and techniques to extract structures from image data, such as in medical and bio-medical imaging.
