PKD was a pharmaceutical company.
Albert Foster was head scientist of the research department at PKD. After approaching the Cyberon vessel and being influenced by the Cyberon, Albert took the vessel to PKD, in order to produce Cyberon. (PROSE: Flight of the Cyberons)
Tom Mordley also worked at PKD. He made a snarky comment to remind Lauren that PKD was sending St John's Hospital lots of money.
After George Cooper died, Tom insisted on doing his autopsy on PKD, rather than on St John's. (PROSE: Cyberon)
The Cyberon who manufactured the drug was located there. After the events at St John's, Tom returned there to collect more doses of Cyberon, however he had to sneak past teams from Geneva and Canary Wharf who had began securing down the facility. Unbeknownst to Tom, he was follow by Louise Bayliss on behalf of P.R.O.B.E., who witnessed Tom kill Albert after he admitted to stop taking the drug. The Cyberon who manufactured the drug noticed Louise, and commanded Tom to kill her, but she was able to restore Tom's freedom by using her gold necklace to interfere with the connection the Cyberon had to Tom's nervous system, and Tom destroyed the Cyberon, but died soon after. The Cyberon drug was secured by UN soldiers and sent to the Vault. (PROSE: The Last Dose)
