Steven G. Johnson '95, PhD '01
Research Interests
 The influence of complex geometries (particularly in the nanoscale) on solutions of partial differential equations, especially for wave phenomena and electromagnetism — analytical theory, numerics, and design of devices and phenomena. (See, for example, photonic crystals.)
 Highperformance computation, such as fast Fourier transforms, solvers for numerical electromagnetism, and largescale optimization.
