[1994-98] Co-instructor for Upper Atmospheric Physics II (EE 586/ASTRO 576), every other spring, with Prof. Michael C. Kelley and others in Cornell's Dept. of Elec. Engr. (see above). ))) Other Relevant Work Experience: [1993-98] Research Associate and Scientific Applications Consultant, Cornell Theory Center, Cornell University. Ongoing research into large-scale numerical simulations and modeling of solar convection complemented educational activities, including training and advising users of the IBM SP series of scalable parallel high-performance computers. Served as advisor for students in CTC's Supercomputing Program for Undergraduate Research. [1991-93] NSF Postdoctoral Research Associate, Cornell Theory Center/Center for Radiophysics and Space Research (jointly), Cornell University. Was awarded a grant from the National Science Foundation in a national competition. Responsibilities: (1), at CTC--to explore new techniques for visualizing the results of fluid simulations; and (2), at CRSR--to extend Ph.D. research on modeling of solar convection (Peter Gierasch, faculty sponsor). [1984-90] Graduate research assistant with Professor R. N. Sudan (thesis advisor), at the Laboratory of Plasma Studies, Cornell University. Gained extensive experience with the CTC from its inception in 1985. Used a variety of computing systems--from vector supercomputers to PC's--in performing research on large-scale numerical simulations of magnetohydrodynamics. Made a number of presentation-quality videos to visualize results. [1984] Laboratory technician, Martin Marietta Laboratories, Relay, MD. Constructed specialized electronics for a microcomputer-controlled spectrophotometer and used it in experiments on photosynthesis biochemistry. (summers, 1981-82) Built and tested experimental solid-state photovoltaic devices made from gallium arsenide and mercury cadmium telluride. [1983] Research assistant, NASA-Goddard Space Flight Center, Greenbelt, MD. Contributed to work in progress on MHD turbulence theory and assisted in applying results to an analysis of plasma data from the Voyager 1 and 2 satellites. Some results of the project were published (see below). ))) Ph.D. Thesis Research: Study of magnetic field dynamics in the solar convection zone by explicit numerical solution of the magnetohydrodynamic (MHD) model equations in two dimensions. The "anelastic" approximation was utilized, which builds a density and temperature stratification into the model but filters out sound waves. Approximate solutions to these partial differential equations were found by a combination of finite-difference and spectral methods. Simulations of the evolution of flow fields and large-scale magnetic structures were computed and compared to predictions from a low-order (Lorenz-type) model of chaotic convection, as well as to solar observations. Because video visualization was an important part of this work, a 20-minute videotape (at that time, a technological feat) was submitted as an accompaniment to the written document. ))) Professional Affiliations: American Astronomical Society (AAS), 1995-; American Geophysical Union (AGU), 1989-; American Physical Society (APS), 1986-2006. ))) Awards: Member of the team winning an IDC HPC Innovation Excellence Award in 2011 for a research project using MATLAB on the TeraGrid (forerunner to Red Cloud with MATLAB). ))) Peer-Reviewed Publications: (** - published with videotape) S.
