Described as a bit eccentric, Rosalind in one of the scientists who works in the BSL5 at Mount Dragon. She is a large and unfriendly woman who borders on rude when communicating with others. She worked with Franklin Burt before his breakdown, and was also instrumental in the development of Mount Dragon's artificial blood project. She has the unconscious habit of rubbing her hands up and down her thighs, which is one of the first symptoms of a reaction to a bad purification process.
