A dedicated area for students in the research group allows quiet working conditions for days of fruitful experimental analysis. The student office is equipped with eight personal desks and desktop computers for research work. A round discussion table in the room facilitates small project meetings. The room is also equipped with a chalkboard and small refrigerator.

Students often make this area their "home away from home," keeping snacks and personal libraries here to enhance their research efforts. We keep a couple of frisbee disks on hand for "down time," sometimes leading to short games of ultimate frisbee on the back lawn of the lab.
