Dr. Daniel Faraday is a fictional character on the ABC television series Lost played by Jeremy Davies. Faraday is introduced in the Season 4 premiere as a physicist from the Queen's College, University of Oxford. He suffers from short-term memory loss, possibly due to his experiments with radioactivity. He is part of the team aboard the freighter Kahana that is offshore the island. Throughout his time on the series, Faraday plays an important role by sharing his knowledge of time travel.
