    Substantially developed a major proprietary statistical software product for high volume, "all-subsets" linear and nonlinear regression. Researched state-of-the-art literature on robust regression, outlier detection, and related topics, and planned software implementation. Researched algorithms of nonlinear programming and other mathematical & computer science topics and planned implementation. Studied/researched mathematical theory of pricing derivative financial securities and recent, advanced financial markets modeling literature. Performed studies and computations in the dynamics, modeling and design of horizontal-take-off spacecraft. Continuing research in the optimization of an advanced concept in numerical methods for ODEs in satellite and planetary orbital applications (extending my doctoral research); explored symbolic computation systems for use in research (especially Mathematica, Derive, and (open source) GiNaC). Studied, implemented, and developed computer systems security and backup/restore/re-installation procedures. Studied/explored C/C++ portability, including GUI issues (STL, MFC, Java, JFC/Swing, V GUI, GTK+, IBM wxWidgets (formerly wxWindows)). Some of this work amounts to all sorts of specialized systems administration types of work with a major emphasis on preparing and maintaining a development environment; mathematics, modeling and other mathematical aspects are a substantial interest. Used gcc (gnu compiler collection, with STL), Borland C++, Symantec/Digital Mars C/C++ (with STL), MFC, V GUI, Java, JFC/Swing, earlier C and C++ packages, Turbo Pascal, Assembler, Windows XP, 2000, 95/98, cygwin, MS-DOS, and a great many development tools. Have also used Mathematica, Derive, GiNaC; (also experienced with ‘office’ tools such as MS Excel and MS Word and OpenOffice Writer and OpenOffice Calc).Also, various other periods.
