A researcher of the Advanced Systems division, Rosalind is a workaholic and efficiency freak. She loves work and detests the limitations imposed by biology. For instance, she'd greatly prefer if sleep was entirely optional, so that she could keep working (say, on more efficient plasma emitters). Beyond that, she's one of the sharpest minds the Institute has, and is primarily responsible for putting Evan Watson's ideas about defeating the Brotherhood into practice. Her biggest achievement was the development of a virus that, with help from a modified synth, could put Liberty Prime firmly under the Institute's control, tipping the scales in their favor.
