I am a full-time faculty person, and I teach mathematics. I primarily teach Calculus, Probability and Statistics, Linear Algebra, and Differential Equations, but I also enjoy it when I get to teach Discrete Structures or Computer Programming for Engineers.
While I love mathematics I have not always been a mathematician. I begin my career by earning a B.S. and M.S. in Electrical Engineering at Purdue University. After getting the opportunity to teach mathematics in Michigan, I shifted my focus to teach and eventually study mathematics. I received a PhD in Applied Mathematics at Bowling Green University. My area of research deals with numerical solutions to conservation laws. If you want to know more about it, just ask.
When I’m not teaching, I am involved in my church, and I enjoy reading sci-fi and fantasy novels, cooking with my wife, watching sports, playing computer games, and cross-stitching.
