Perna was a Hoffan scientist who worked with Dr. Carson Beckett on developing the Hoffan drug which would hopefully protect the user from Wraith feeding. During their time collaborating on the project, the two developed a strong appreciation for each other's skills, with there being a strong implication that their feelings went beyond professional admiration. After the trials on Merell were successful, she was part of the first group to be inoculated with the drug. Unfortunately for her, the drug had a 50% mortality rate which was only discovered after she was inoculated, and she died, her last words to Beckett being that she wished she could have seen Atlantis before her death.
