I have a BS and MS in Physics from Georgia Tech and a Ph.D. in Mathematics from Carnegie Mellon University. I worked for 30+ years as an applied mathematician for Westinghouse in Pittsburgh. During that time I also taught as an adjunct professor at CMU and at Duquesne University in the Mathematics Departments. I have tutored many high school and college students over the years and enjoy doing so, especially seeing "the light come on"....
