Steven G. Johnson

Steven Glenn Johnson (born 1973)^[2] is an American applied mathematician and physicist known for being a co-creator of the FFTW^[3][4][5] 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.^[6]

While working on his PhD at MIT, he developed the Fastest Fourier Transform in the West (FFTW) library^[3] with funding from the DoD NDSEG Fellowship.^[7] Steven Johnson and his colleague Matteo Frigo were awarded the 1999 J. H. Wilkinson Prize for Numerical Software for this work.^[8][9]

He is the author of the NLOpt library for nonlinear optimization,^[10] as well as being the co-author of the open-source electromagnetic softwares Meep^[11] and MPB.^[12] He is a frequent contributor to the Julia programming language, and he has also contributed to Python, R, and Matlab. He was a keynote speaker for the 2019 JuliaCon conference.^[13]
