Professor Ellen Anders is an intelligent civilian researcher. With PhD’s in biology, anthropology, and psychology, Prof. Anders is the preeminent expert in theoretical xeno-biopsychology. Anders has an IQ of 180 and was the student of Dr. Catherine Halsey, progenitor of the SPARTAN II program. She appears to hold a particular grudge against the Covenant, and like many involved in the war effort considers her work to be for the good of humanity as a whole. She somewhat personifies the 'absentminded professor' stereotype, with a characteristic disregard for personal safety.
