I am retired. I have a strong technical background. I spent the majority of the last 30 years or so in technical leadership rather than hands on development of technical capabilities.
In regards to education, I have a BS in Math, Physics, Computer Science and a PhD in Math. Early in my career I developed Flight Simulator Visual Systems, Software Systems Development, Discrete Event Simulations, System Analysis, and so on. Later, and for the most part, I led teams in large scale leading edge system development and advanced development (R&D).
I kept up with all traditional programming languages as well as Matlab and Mathematica. I have certainly forgotten more than I know.
I developed an affinity for Matlhematica and would now like to become proficient with this tool. At this time, I am not looking for job opportunities.
