The 10th?president of the university, and the first leader with an engineering background, said that he decided to leave his role in order to focus on ¡°what brought me to Stanford ¨C teaching and research¡±.

Dr Hennessy has served in academic leadership roles for more than two decades at Stanford, which is ranked fourth in the latest?Times Higher Education World University Rankings.

Addressing Stanford¡¯s faculty senate, where he received a prolonged standing ovation, Dr Hennessy said: ¡°The time has come to return to what brought me to Stanford ¨C teaching and research. Maintaining and improving this university is the work of many people, and I am deeply appreciative of the dedication of so many colleagues to Stanford and its students.¡±

Since becoming president in October 2000, Dr Hennessy placed an emphasis on interdisciplinary teaching and research that was reflected in a physical transformation of the campus, designed to heighten opportunities for intellectual collaboration between faculty and students.

¡°It has been a remarkable run, one of the greatest not only in Stanford¡¯s history but also in the annals of American higher education.¡±
