Professor of Applied Mathematics, Department of Mathematics
Steven Johnson is a professor of applied mathematics in MIT’s Department of Mathematics. He works in the field of nanophotonics — electromagnetism in media structured on the wavelength scale, especially in the infrared and optical regimes — where he works on many aspects of the theory, design, and computational modeling of nanophotonic devices, both classical and quantum. He has published more than 200 papers and 25 patents, including the second edition of the textbook Photonic Crystals: Molding the Flow of Light. He has also distributed several widely used free-software packages for scientific computation, including the MPB and Meep electromagnetic simulation tools and the FFTW fast Fourier transform library (for which he received the 1999 J. H. Wilkinson Prize for Numerical Software). He earned a BS in physics, mathematics, and electrical engineering and computer science, and a PhD in physics, from MIT.
