About me:

I first joined the Mathematics department at MC in 1995, and hold the rank of Professor.

I am a proud member of the MC chapter of the American Association of University Professors, and I currently serve as past president of this organization. I have also served on the negotiating team for over a decade, and held numerous other offices before being elected to my current position.

Some of my other involvements at the College include working with the Honors Program, as a member of the honors curriculum committee and previously as Program Coordinator for the Rockville Campus, and as a charter member of the Bicycle Task Force in which I have worked with representatives from the College community, the city, county, and state, to help promote bicycling and bicycle safety.

When not at the College I enjoy playing and coaching a variety of sports and games with my sons.
