Doctor McCormick is a female Tau'ri scientist.
She developed a plan with Dr. Williams to dial Destiny's Stargate back to Earth while it was recharging inside a Star. She switched bodies with Chloe Armstrong to carry it out along with Colonel David Telford. However, Telford's actions drew some concern, particularly from Dr. Nicholas Rush and Adam Brody, who felt that it posed the risk of destroying the ship. After Rush and Brody faked a catastrophic chain reaction in the Gate, she and Telford turned off the Long-range communication device to escape the ship. (SGU: "Earth")
