In 1989, the Board of Trustees directed then-Tufts University president Jean Mayer to initiate a search for a new leader of the Faculty of Arts and Sciences (which at the time included the College of Engineering) with a vice presidential title. According to the second volume of Tufts official history, the then-chair of the Board of Trustees, Nelson Gifford, allegedly saw the person hired to fill the new post of academic vice president for arts, sciences, and technology (redesignated vice president for arts, sciences, and technology in 1991 and then vice president for arts, sciences, and engineering in 1999) as a potential successor to Meyer. Two men held the vice presidency: Robert I. Rotberg, formerly professor of political science at Massachusetts Institute of Technology (1989 - 1990) and I. Melvin Bernstein, formerly professor of mechanical engineering and provost at the Illinois Institute of Technology (1990 - 2001). In 1999, the College of Engineering was renamed the School of Engineering and took responsibility for all graduate engineering programs from the Graduate School. As part of the same reorganization, the Trustees redesignated the Faculty of Arts and Sciences as the "Faculty of Arts, Sciences, & Engineering" and formally created a School of Arts and Sciences (encompassing the College of Liberal Arts and Jackson College and the Graduate School of Arts and Sciences). After the retirement of President John A. DiBiaggio and Bernstein's appointment as provost of Brandeis University in 2001, Tufts new president Lawrence S. Bacow abolished the vice presidency for arts, sciences, and engineering and created the post of dean of the School of Arts and Sciences. Developmental biologist Susan G. Ernst held the position of dean of the School of Arts and Sciences, from September 2001 until she returned to full-time teaching and research in the Biology Department in September 2005. She was succeeded as dean by psychologist Robert J. Sternberg, formerly the IBM Professor of Psychology and Management at Yale University. Sternberg remained in that position until 2010, when he departed to become Provost at Oklahoma State University. He was succeeded by neuroscientist Joanne Berger-Sweeney, formerly the Associate Dean of Wellesley College.
