University of Houston
Since 1997, the President of the University of Houston has also held the position of Chancellor of the University of Houston System, thus making it a dual-office. Note: The defunct Chancellor of the University of Houston position should not be confused with the current position of Chancellor of the University of Houston System. While one position refers to a leader of the single flagship institution of the University of Houston System, the latter refers to the leader of the entire University of Houston System consisting of several other universities besides the flagship institution.
