A young and capable S.G.C. technician, Simmons is one of the original gate operators. He has also had a long-standing crush on Samantha Carter. Simmons has also assisted in the S.G.C.'s initial mission analysis of various items brought back through the gate. Proximity to one of these devices, an alien orb, infected him and the rest of the base with an alien pathogen. Others were given tetracycline to stop ebb the virus -- but Simmons is allergic to it, and lay untreated. This threatened his life, but he managed to survive the experience. Simmons did not appear for nearly four years, possibly implying that he was transferred off the base and then back. When Anubis attacked Earth's Stargate, Lieutenant Simmons was assigned to determine why the Goa'uld was able to maintain a stable wormhole for more than 38 minutes.
