The primary supplier of water and edible foodstuffs for the Institute, this division is filled with hydroponic farms and even a small gorilla habitat where the scientists have recreated Old World gorillas. Its head is Clayton Holdren.
The FEV Lab can be accessed by going down the hallway to the right of the entrance, through the store room and the corridor beyond. It is beyond a Novice-locked door.
The BioScience area focuses on the hydroponics and preserve area, with the adjacent rooms containing workshops, laboratories, and store rooms, as well as the access point to the old FEV lab.
The Institute Bioscience apppears only in Fallout 4.
