Professor Steven G. Johnson is a principal investigator in the Research Laboratory of Electronics (RLE) at the Massachusetts Institute of Technology (MIT). He received the B.S. and Ph.D. in physics from MIT in 1995 and 2001 respectively. From 2001 to 2003 he was a postdoctoral associate at MIT, and was a postdoctoral associate at Harvard University in 2004 before joining the MIT faculty as Assistant Professor of Applied Mathematics in the same year.
Professor Johnson co-developed the FFTW fast-Fourier transfrom library, for which he was the co-recipient of the 1999 J. H. Wilkinson Prize for Numerical Software. His current research interests focus on two areas: photonic crystals and electromagnetism in structured media; and high performance computation, from fast Fourier transforms to large-scale eigensolvers for numerical electromagnetism.
