Swenson was a science officer stationed onboard the USS Enterprise-D in 2364. This year, a martial arts competition was to take place on the ship; among the participants were Swenson, Minnerly and Natasha Yar. While Yar believed she could easily defeat Swenson in Aikido, she was worried about meeting Minnerly in kickboxing. (TNG: "Skin of Evil")
