Dr. Zev Cohen

Dr. Zev Cohen is a scientist at Noveria's Peak 15 research facility. He can be found in the medical bay, tending to his fellow scientists.

Dr. Cohen's team was working on a biotoxin to kill the Rachni, largely as a safety measure. But Binary Helix saw no profit in a toxin that only killed one near-extinct species, so Cohen's team developed it to affect more species. While they were working on the biotoxin, Mira's core went down and quarantine was broken. The biotoxin infected several of the scientists, but was not contagious. Dr. Cohen had to take over after the station's doctor was killed; he had little medical training but did his best to take care of the others. He was also tasked with administering stims to the guards on request. Cohen had little choice because the perimeter needed to be maintained, but he became worried about how strung-out Captain Ventralis and his people were: the guards just weren't getting any sleep.

When Commander Shepard's squad arrives, Cohen asks for help in making the biotoxin cure because he can't get into the quarantined lab. In return he can offer his pass to the secured maintenance area at the back of the station. If Shepard makes the cure, the squad is ambushed by Alestia Iallis, but Dr. Cohen is as shocked as they are that she turned out to be a commando, and explains that Alestia was recently transferred there by Saren Arterius. He is very grateful for the commander's help and offers a reward - Shepard can use Charm or Intimidate to get some extra medi-gel packs from him. There is also a Mira terminal in the medical bay beside him, which can administer emergency first aid to the squad.
