In 2006, he began writing his dissertation under supervision from political science professor Frank Decker, which he has so far not completed due to his political activities. While studying Lindner became a reserve officer in the Air Force. In 2002, he was promoted to First lieutenant (Oberleutnant) in the Reserve. In 2008 he was a liaison officer to the state command Landeskommando of the state of North Rhine-Westphalia in Düsseldorf.
