• Expert in developing physics-based algorithms involving high-performance computation• Expert in wave mechanics (Schrodinger/quantum & Maxwell/optical) including scattering theory• Performing tomography & metrology of microchip structures at KLA Corp using nonlinear optimization• Motivated to use my skills for projects that benefit the greater good• Seeking to join a team doing physics-based algorithm development with rigorous programming practicesI produce cutting-edge solutions for important physics problems. I modeled high-dimensional quantum- mechanical waves (Schrodinger equation) in Atomic, Molecular, and Optical (AMO) physics (2002-2015) and I model three-dimensional waves of light (Maxwell's equations) in my current career doing optical and x-ray metrology at KLA Corporation (2016-current).In AMO physics at Lawrence Berkeley Laboratory, I solved the Schrodinger equation for quantum waves with few to hundreds of independent variables in many contexts, producing the fastest Schrodinger solver for highly-excited time-dependent quantum mechanics of electrons in atoms and small molecules in the world, https://www.github.com/LBNL-AMO-MCTDHF/V1.At KLA Corporation, I do metrology (measurement) of nanometer-size semiconductor (microchip) structures. Doing metrology, I solve the inverse scattering problem: Our machines take measurements of photons scattered by microchip structures, and I develop algorithms that use those measurements to infer the shape and size of the nanometer-size microchip structures. Given measurements with 100-1,000,000 independent variables, I create new methods for solving Maxwell's equations with 3 independent variables, and I use them to solve nonlinear optimization problems with 10-40 independent variables. At KLA Corp., I create new methods for solving Maxwell's equations, and new methods for the nonlinear optimization problem, the inverse scattering problem, of metrology.I am an expert in wave mechanics (quantum mechanics and optics in particular) and in the development of efficient numerical algorithms for high-dimensional physics problems using high-performance computation, including nonlinear optimization.I want to be part of a team doing scientific work with long-term value, making the world a better place, producing robust, reliable computer codes for the future according to rigorous programming practices.

Listed skills include Numerical Analysis, Scientific Computing, Physics, Parallel Computing, and 34 others.
