Starfleet councillors suggested to her that she might want to go into the diplomatic corps but Autumn wanted the adventure of space. So in she went for officer training. She decided to major in medicine and languages. She got her doctorate degree within the two years that she was at the Academy. Autumn wasn't one to sit around and sit on her hands so in her first year she took on an extra course load with the aim of graduating top of her class.

Autumn was very determined to make friends in her new life and was soon going out and partying. She shared her room with human female by the name of Riana Parstran from the south of France. They shared a two bedroom flat with self contained kitchen and lounge. Riana's room was always tidy and to Starfleet standards. Autumn's room was not messy just cluttered with things she had found and collected over the years. Riana gave her the nickname Kender after a character in a series of books she had been reading. They were good friends and, even though Riana left Starfleet halfway through her training to join up with a rebel group called The Maquis (fighting against the Cardassians and Starfleet because of the DMZ), they used to communicate through Autumn's parents (unknown to Starfleet) but during the Dominion War the Maquis was wiped out by the Dominion, and Autumn hasn't heard from Riana since; though she hopes that her friend was one of the lucky ones that escaped from the Dominion.

Autumn didn't get another room mate during her training a fact that made the guys at the academy very happy. Not that it got them anywhere! She dated very often but never had a serious relationship until her second year. His name was Carlos Vaughan he was a student at the academy and they both soon found themselves being put together in training as well in social situations.. The relationship lasted about 6 months and when she broke it off things got UGLY. Carlos not at all content with the way things had happened took to the old routine of stalker. Autumn took the problem to the security office and Carlos was soon under control.

Four months later Autumn graduated second in a class of 150. She finished her training in two years. Autumn was assigned to the USS Reliant for a two-year tour of duty. She served as one of the ships Doctors.

After a few months she found herself bored with the routine and the people and was soon up to some practical jokes. These included the Captain being locked out of his ready room and the science station on the bridge being covered in Paper-Mache after the chief science officer Lt Commander Julies Wilson insulted her one evening while he was drunk. He called her a whore. Her excuse was that he had deserved it and that if he couldn't keep his mouth shut and his hands to himself she would do more the Paper-Mache his station next time. After that incident Autumn found her self being avoided by the crew even by her room mate, Autumn who thought her room mate was a bitch didn't give it another thought and programmed the transporter to transport her room mate's clothes into space, every single last one . It took her room mate three hours to get them back. Autumn received no reprimand for this. It looked like a simple transported malfunction! This made it even worse for her in the friendship area. As she hadn't had many friends on bored in the first place this didn't bother her.

After two years on the reliant she put out a transfer request. 'Anywhere but here' was written on the bottom of her request form. The request was granted and she is now on her way to serve on the USS Galaxy under the command of Captain Robert Edward Lee Price. Autumn hopes to make friends and this time not to get into trouble. She hopes that any room mate she gets is a nice person and that they get along

Autumn was promoted to Lieutenant junior grade a short time after coming to the USS Galaxy. Autumn also met and fell in love with Wilhem Quevvenson, they married in late 2377. Autumn and Wil now have a pet panther cub by the name of Summer Night.

In early 2378, Autumn was promoted to full Lieutenant and made the Assistant Chief Medical Officer on board the USS Galaxy.
