Lindsey Novak is an engineer who turned down an offer to join the original expedition to Atlantis. She has an acute case of the hiccups when she's frightened, an annoyance that almost destroyed her PhD presentation.
Lindsey was aboard the Prometheus when it attempted to make a voyage to the Pegasus galaxy to assess the Atlantis expedition's situation (No one had heard from them since their departure). She was one of the officers offloaded to a Goa'uld Al'kesh by Vala Mal Doran who intended to sell the Prometheus to a fellow arms dealer, Tenat. She and MSgt. Walter Harriman repaired the Al'kesh and followed Prometheus. Eventually, Dr. Daniel Jackson was successful in securing the ship, turning it around to pick up Novak and the others who were stranded. Prometheus did not make it to Atlantis. (SG1: "Prometheus Unbound")
Almost half a year later when the Earth ship Daedalus was completed, Novak served as engineer alongside the Asgard Hermiod. She occasionally frustrated the alien concerning matters relating to weapons deployment using Asgard transporters. But at least she had gotten over her hiccups. (SGA: "The Siege, Part 3")
When The Trust planted a bomb in Atlantis, Novak received the message from Stargate Command to relay to Atlantis. Later, she was interrogated by Dr. Elizabeth Weir and mentioned that Dr. Peter Kavanagh was always poking around in the Daedalus computers. (SGA: "Critical Mass")
When Teyla Emmagan offers to accompany him, Hermiod is surprised as only Novak amongst the crew of the Daedalus ever volunteers to spend time with him. Hermiod is shown to find Novak's awkward affection for him to be vexing at times. (SGA: "Hermiod's Last Mission")
During the Battle over the Outer Rim Planet, Novak struggles to repair the Daedalus sublight engines so that the ship can aid the George Hammond in battle against a hive ship and a Wraith cruiser. When Caldwell calls her to tell Novak that they need sublights back, a frustrated Novak tells him that she's trying but the engines are just not responding, causing Novak to suspect the ignition system might be shot. Novak tells Caldwell that she's not sure she can get the sublight engines back online without major repairs and he tells her to do what she can as at the moment, all the Daedalus can really do is watch the battle. Novak acknowledges this and Caldwell suspects she's wishing Hermiod was there to mutter in Asgard and come up with some brilliant solution. Finally, Novak manages to restore sublight engines in time for the Daedalus to reengage the hive ship, enabling Colonel Samantha Carter to destroy the hive ship. (SGA: "Allegiance")
