I have degrees in mathematics from MIT and Cornell, and a PhD in Modeling & Simulation from the Univ. of Central Florida. I've tutored mathematics since high school ( 1975). I've been an industrial mathematician/programmer for decades. I've also been a professor of mathematics. My English verbal skills are excellent (I can provide published technical writing samples if requested). Background in signal processing, statistics, mathematical logic, group theory, and much else. Expert in MATLAB and AMS-LaTeX.
