Steven G. Johnson is an American mathematician known for being a co-creator of the FFTW[1][2][3] 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[1] with Matteo Frigo; they were awarded the 1999 J. H. Wilkinson Prize for Numerical Software for this work.[4][5]

He is the author of the NLOpt library for nonlinear optimization. He is a frequent contributor to the Julia programming language, and has also contributed to Python, R, and Matlab. He will be a keynote speaker for the 2019 JuliaCon conference.[6]
