Aerospace Engineer, developer of tools for Industry

My career has been spent developing analysis tools, predominantly for aerospace. I have maintained and updated monolithic programs for the design and performance analysis of solid rocket motors and liquid rocket engines. I developed several frequency domain acoustics codes, based on ARPACK and P-ARPACK, using open-MPI for parallel processing. One acoustics code is used to evaluate how sounds moves inside of combustion chambers under the influence of a steady flow field (subsonic - supersonic), which is helpful for combustion stability analysis. Most of this work was performed using Fortran.

NASA JSC requested development of a MS Excel Add-In that converted NASA Glenn's chemical equilibrium code into an Excel spreadsheet function. This has been turned into a commerical product, Cequel, which I now own and maintain for a growing user base (see www.praqsys.com). It includes not only a function, but several Wizards with a database of reactants to help put the function in the spreadsheet (where it can then be copied using cell references). This was an unholy mix of Visual Basic for Applications, Fortran (gfortran!), and a little C to tie it together.

I also tutor math (Geometry, Trigonometry and Calculus) through tutor.com.
