“It’s not so important to know what you are doing; it is much more important to know exactly where you stand.”

Samuel "Sam" M. Politz

I especially enjoy teaching when I get to know the students well and can see them learn. WPI gives me the opportunity to do this in the project system. I love teaching students in the research lab, seeing them learn that things in the real world are much more interesting than the textbook view. I get excited when I see something in the lab that doesn’t make sense. When I have made discoveries that turned out to be important, it was like walking through a room at night with the lights off. After bumping into a lot of furniture (ouch!), one eventually finds the light switch. When students “get” that, this is what making discoveries is about. It is a wonderful thing to witness.

Spotlight On: Current Research

Our laboratory studies the genetic control of surface composition in the nematode Caenorhabditis elegans. We are interested in this feature of postembryonic development because of its adaptive significance in nematode parasitism.
