Wharton dean Robertson to step down in 2014

Thomas S. Robertson will resign as dean of the Wharton School, the prestigious business school at the University of Pennsylvania, in June 2014.

He made the announcement in a letter to the faculty Wednesday in which he said he intended to return to the school's marketing department to teach and pursue research.

"It is fulfilling to be Dean at Wharton – both exciting and challenging – and I believe that I have accomplished what I set out to do," Robertson wrote in the letter.

Named dean in June 2007, Robertson had succeeded Patrick Harker, who left to become president of the University of Delaware.

During Robertson's tenure, the size of the faculty increased to 478, including 230 tenured and tenure-track professors, from 435 people.

He also noted the following as accomplishments:

We weathered the financial crisis, exceeded our campaign fundraising goals, regained our executive education momentum and found the resources to renovate Vance Hall, build an addition to Steinberg Hall-Dietrich Hall and to move to a signature new campus in San Francisco.

Wharton currently has 4,835 students enrolled in degree programs, including 1,683 in MBA programs and 426 in executive MBA programs.
