I have been teaching at IMSA for last twelve years. I used to teach both Mathematics and Computer Science. But the last several years, I have been teaching exclusively Computer Science. I have designed several new courses while at IMSA. I have taught at two other high schools – Morgan Park High School, Chicago and Proviso Mathematics and Science Academy, Forest Park. Prior to becoming a teacher, I worked at AT&T and Lucent Technologies for twenty three years. I did my MS and PhD from University of Texas at Dallas in Operations Research. My undergraduate degree is in Mechanical Engineering.
