Dr. Zev Cohen is a human microbiologist at Noveria's Peak 15 research facility. He can be found in the medical bay at Rift Station, tending to his fellow scientists, beside a Mira terminal which can administer emergency first aid to the squad. When Commander Shepard's squad arrives, Cohen asks for help in making the biotoxin cure, because he cannot access the quarantined lab. In return, he can offer his pass to the secured maintenance area at the back of the station, warning that Ventralis' men are getting more on edge since Shepard arrived.
