Faculty & Staff

All of GCC’s Physical Sciences residential faculty hold master’s degrees or higher. Our instructors are published researchers, members of national science organizations, and former employees of NASA, the US Geological Survey and other private industry companies. They are also dedicated educators who want to see you succeed. Most teach lectures as well as the lab courses. You’ll find their office hours posted and, very often, their doors open.
