Josh Randall was a student at the University of East Wessex.
However, the drug also resulted in him becoming psychotic. He was going to allow Finer's time machine to run unchecked, collapse the universe and become God. The Fourth Doctor and the TARDIS were able to prevent this. A new timeline was created where Randall never developed psychic powers and had only a passing interest in the paranormal.
