John Strain (mathematician)

John Andrew Strain is a Professor of Mathematics at the University of California, Berkeley. His areas of interest are Applied Mathematics, Algorithms, Numerical Analysis, and Materials Science.^[1] John Strain received his PhD in Mathematics from the University of California, Berkeley in 1988 working with his advisor Alexandre Joel Chorin.^[2] His dissertation paper was on the numerical study of dendritic solidification. Notable publications include Piecewise-polynomial discretization and Krylov-accelerated multigrid for elliptic interface problems,^[3] Locally corrected semi-Lagrangian methods for Stokes flow with moving elastic interfaces,^[4] Locally-corrected spectral methods and overdetermined elliptic systems,^[5] Fractional step methods for index-1 differential-algebraic equations,^[6] and Growth of the zeta function for a quadratic map and the dimension of the Julia set.^[7]
