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. He is a frequent contributor to the Julia programming language, and has also contributed to Python, R, and Matlab. He was a keynote speaker for the 2019 JuliaCon conference.[10]
