I'm a Medical Doctor working aboard Space Station 13 in the medbay. I answer to the Chief Medical Officer, and my coworkers include the Chemist, the Virologist, the Psychologist, and the other Medical Doctors.  I got my medical license and hoped to work in a proper hospital, but I'm stuck working in this glorified emergency room.
I keep the crew healthy and alive, heal the wounded, and revive the dead. I'm an expert surgeon under stressful conditions.
