Dear Students, During a tour of the building today, Professor Sands noticed items (i.e., coffee mugs, etc.) sitting on the window ledges outside some of the labs. This may have negatively impacted our visitors with an unprofessional atmosphere. If possible would you please leave your drink items in your office and not outside the labs?
