Graham Simmons

Lieutenant Graham Simmons is a member of the SGC, assigned to the base. He has assisted in the scientific research of off-world artifacts such as the orb from P5C-353, from which he became infected by the microscopic organisms. His condition was serious due to an allergy to tetracycline, however he recovered when alternative antibiotics became available after the base lockdown ended. As a technician, Simmons has also directed the diagnostics, dialing, and control of the stargate.
