I love learning and I love watching students learn and succeed! Math, Biology and Computers are my favorite subjects. I obtained my Ph.D. in Biology studying the nuclear organization of DNA and how that affects gene expression. I have 2 sons who are 16 and 9. I teach Biology for science majors and sometimes Genetics at TCC-Northeast Campus, where my wife, Kristin, is a Biology Professor and Co-chair of the Biology department. I love watching and participating in sports (particularly biking, golf, swimming and tennis).
