Intrigued.  Let me give this a shot.

Name: Maria Mitchell Astrena

Biological Age: 41

Nationality: Second Lagrange Observatory

Preferred Position: Chief Navigations Officer

Bio: 

People who work in Second Lagrange Observatory have a reputation: sober, competent and humorless.  People born there ... well.

Lagrange 2 is permanently shaded by the earth's shadow.  This makes it perfect for experiments so sensitive that they could be disrupted by a stray photon from the sun.  It also makes it perfect for exacting stellar observations without interference.  Such work requires a steady hand and an absolute focus.  A sense of humor is an optional extra that most can't afford.  The residents have accepted the unofficial designation of Second Lagrange as "Where the Sun Doesn't Shine" without a hint of a smile.

Born from a rare relationship on the observatory itself, Maria was born looking up at the Earth's darkside.  Not surprisingly, she decided to look in the other direction.  Named after the famed astronomer, she grew up carefully measuring the stars.  

Navigating a starship requires an absolute dedication to precision and efficiency.  On a self-sufficient ship where 80 people require a constant stream of resources to survive, any amount of waste is too much.  At the same time, it requires an intuitive grasp of the technology that controls the ship's movement.  Many things - like time dilation and drift - are too complicated to build equations around in a way that humans can grasp them. AIs can only do so much. Playing it by "feel" is the only workable solution.

Maria combines both into a single stone-faced package.  The courses she plots will show up in the next generation's textbooks.  Her crew - the helmsmen and assistant navigators - admire her skills even as they mock her inability to recognize a joke.[/hider]
