Steven Glenn Johnson (born 1973) is an American mathematician known for being a co-creator of the FFTW library for software-based fast Fourier transforms and for his work on photonic crystals. He is professor of Applied Mathematics and Physics at MIT where he leads a group on Nanostructures and Computation. While working on his PhD at MIT, he developed the Fastest Fourier Transform in the West (FFTW) library with funding from the DoD NDSEG Fellowship. Steven Johnson and his colleague Matteo Frigo were awarded the 1999 J. H. Wilkinson Prize for Numerical Software for this work.
