Professor
James A. Sethian is a Professor in the Department of Mathematics at the University of California, Berkeley , with additional affiliation at Lawrence Berkeley National Laboratory . His work focuses on developing and applying Level Set Methods and Fast Marching Methods to track evolving interfaces across diverse scientific domains. Education: Ph.D. in Applied Mathematics , University of California, Berkeley (1982) B.A. in Mathematics, Princeton University (1976) Research spans Applied Mathematics , Computational Physics , and Numerical Analysis , with applications in Semiconductor Manufacturing , Fluid Dynamics , Medical Imaging , Image Processing , Seismic Analysis , and Optimal Control . His publications demonstrate expertise in modeling interfaces that develop sharp corners, break apart, and merge, particularly through PDE-based numerical techniques. Key contributions include algorithms for noise removal , minimal surface computation , and multi-layer coating flows . As a mentor, he has advised numerous PhD students in computational methods and applied mathematics, including Robert I. Saye , Jon Arthur Wilkening , and David Layne Chopp . Projects under his leadership integrate ViscoElastic Flow , Tumor Modeling , and Robotics via curvature-driven evolution and interface tracking.
