Earned Bachelor degrees in Math (advisor Daniel Kleitman) and Physics (advisor Philip Morrison) at MIT (1974), astrophysics thesis on the optical variation of quasar 3C345. Earned PhD. in Physics (advisor Peter vanNieuwnhuizen) at Stony Brook: was vanNieuwnhuizen's first graduate student, thesis (1979) was on construction of Lagrangians and Finiteness calculations in Supergravity and Extended Supergravity. Did a theory Post-doc at Fermilab, performing two-loop calculations and renormalization for the "penguin diagrams" in the standard model. Focused on Grand Unified Theories; developed Young-tableau-like methods for determining the decomposition into irreducible representations of Kroenecker products of representations of Lie groups (other than SU(n), which was well known previously). Theory post-doc at University of Pittsburgh, moving toward Lattice Quantum Chromodynamics (LQCD) calculations. Permanent position at Fermilab from 1983 to 2012, starting int he Advanced Computing Program where we developed the first farms of single-board computers - these were used for analysis of High Energy Physics fixed-target and collision events. Key architect and primary software developer for the ACPMAPS supercomputer, used for LQCD calculations. Applied Scientist II and member of the Computing Division from 1988 onward. Led groups including the principal (non-computer) scientists participating in the C++ standards committee; responsible for much of the content of the Special Functions and Random Numbers portions of the standard library in C++11. Currently a principal software engineer at Thales Visionix, where we make helmet-mounted cueing systems for aircraft.
