Brought in as a civilian specialist for the first mission to Abydos, Dr Jackson's role was to decipher the characters on the StarGate and return to team home safely. Dr. Jackson had a large part in destroying Ra, saving his wife-to-be Sha'uri.

When O'Neill and the first team returned to Earth from Abydos, Dr. Jackson remained behind with Sha'uri. Later when the Goa'uld return to Abydos after they learn of the death of Ra, Sha'uri is captured by the Goa'uld and implanted with a symbiote. Dr. Jackson returned to earth to provide the necessary skills to help SG-1 to find his wife.

Doctor Jackson has a Ph.D. in Linguistics and another in Anthropology, speaks over 20 languages, including several dead languages.
