Serving on the Enterprise
As some point during her life, Nhan joined Starfleet where by 2257, would obtain the rank of Commander, and was serving as an engineer aboard the USS Enterprise under Captain Christopher Pike. (DIS: "Brother")
Serving on the Discovery
Along with Evan Connolly, she accompanied Captain Pike onto the USS Discovery when the Enterprise suffered a malfunction. She was also a part of the team that investigated the crashed wreckage of the USS Hiawatha. (DIS: "Brother")
Nhan accompanied Michael Burnham and Airiam to board Section 31 Headquarters, which led to a series of events where she had to eject Airiam from the airlock before Control could take the Sphere's data. (DIS: "Project Daedalus")
When it was decided that Burnham would take Discovery forward to the 32nd century to prevent Control from seizing the Sphere data, Nhan decided not to resume her post on the Enterprise, but was among a group of crewmembers volunteering to join her, even knowing that there was no chance to return. (DIS: "Such Sweet Sorrow")
Nhan helped Philippa Georgiou in neutralizing Leland (reanimated by Control), when "he" boarded the Discovery to take the Sphere data. After the Discovery disappeared from its original timeframe, Nhan, along with the rest of the volunteering crew, was presumed dead by Starfleet, based on the testimonies of the USS Enterprise senior officers. (DIS: "Such Sweet Sorrow, Part 2")
"I see where the Federation puts its pennies."
"Do not covet thy neighbor's starship, commander. Besides, we've got the new uniforms."
"And lovely uniforms, they are. Captain."

"I just...Look, my job is to preserve as many lives as possible at any cost. But what you said at the service...It is hard to let go."
"You did the right thing. I'm grateful you were there."
"Strange way to get to know someone, but...after seeing how hard you fought for her, the real her...Let's just say I'm grateful you were there, too."
Nhan was portrayed by actress Rachael Ancheril.
