|Position||Lieutenant junior grade|
Aili Lavena was a female Selkie who served in Starfleet in the late 24th century. In the late 2350s, Lavena had an affair with her future Captain, William T. Riker, while during her amphibious stage.
In 2379, Ensign Lavena signed aboard the USS Titan, which was under the command of her former lover, Captain Riker, although he didn't recognize her at first. She served as the chief flight controller on the alpha shift. Due to her unique biology, her quarters were specially adapted and filled with ocean water from Pacifica so that she could be comfortable during her off hours.
During the Borg's invasion in 2381, Lavena was on duty at the Bridge helm station when former Earth Starfleet Captain Erika Hernandez escaped the clutches of the Caeliar on New Erigol and promised to aid the Titan in departing as well. As Hernandez adjusted their deflector, she ordered Lavena to stand by at their best nonwarp speed. Erika allowed Captain Riker to give the word to depart, and as soon as he did, Lavena pressed the panel to fire the impulse engines at full power, taking the ship into the aperture of the subspace tunnel leading to the Azure Nebula.

After the events on Droplet, Aili was promoted to lieutenant junior grade in 2381.
