Doctor Duff

Doctor Duff is the wife of Professor Scara and a scientist running the Science! Center in Diamond City $$

Background
Doctor Duff works at the Science! Center and is described as "flitting from experiment to experiment", in contrast to her wife Professor Scara, who focuses on progressing research to completion before moving on. Duff's experiments explore different scientific fields, including biology, medicine and chemistry. She teaches free biology lessons to those who visit, often teaching to the children from the Diamond City Schoolhouse.

She is knowledgable about different types of ionizing radiation and their effects, including the Gamma Rays associated with the bombs of the Great War and how creatures have adapted to it. She determined that these adaptations allowed Bloatflys to develop a unique gland that maintains their balance and speed despite their large size. Duff also theorizes that the Institute grows Synths "from the ground using recombinant plant nuclei."

Professor Scara is often annoyed with Duff, who writes that she leaves her experiments on her lab bench, causing them to spill over her work. Scara also writes that she only agreed to stay with Duff because her laboratory contained the gear she uses for her projects. Duff has repeatedly rearranged Scara's workspace to surprise her, with Scara stating that she has a "specific way of organizing" her belongings that she doesn't like being messed with.

During the quest Liberty Reprimed, Duff will tell the Sole Survivor that Professor Scara has gone missing, expressing that the two are close and that losing her would be a "great loss to the scientific community." If Professor Scara is used to complete Liberty Prime, Scara will state that Elder Maxson allows Duff to visit her.
