Dana Kathrine Scully was born on February 23, 1964. She has one older and one younger brother, and an older sister, Melissa. Her father died early in 1994.

Against her parent's wishes, Scully went from medical school to Quantico, where she taught for two years at the FBI's training academy. From there she was assigned to work with Fox Mulder and the X-Files in order to keep an eye on him and determine whether he is perhaps too obsessed with the X -files.    

Agent Scully is skeptical of anything paranormal, believing that everything has a logical, scientifically-quantified explanation.

Over the years that they have worked together, her trust in his instincts and her respect for his integrity have eroded her skepticism. Scully is a full partner in the X-Files, focusing on assembling the hard evidence that will prove the truth is out there.
