Musa-Umar gave the advice while taking over the affairs of the institution from the outgoing vice-chancellor, Prof. Abdullahi Mahdi, on Tuesday in Gombe.
He called on the staff to make more efforts to ensure academic excellence and discipline in the university.
He assured the government and people of the state, as well as staff and students of the university that he would sustain the success recorded by his predecessor.
The vice-chancellor lauded his predecessor for laying a solid foundation which made the institution a force to be reckoned with in spite of the challenges he encountered.
Earlier, Mahdi thanked the staff, students and other stakeholders for their support and cooperation which, he said, enabled him to succeed in the university.
He said that as a human being, he could not have pleased everybody, and asked for forgiveness in the areas where he might have offended anybody.
