HARRISBURG, Pa (AP) — The chancellor who led Pennsylvania’s state-owned university system for six years through the challenge of consolidating says he’ll leave the post in October. Daniel Greenstein said in an online post yesterday he informed the board of governors of the Pennsylvania State System of Higher Education he will leave the job October 11. He called it “one of the most challenging decisions” of his career. Greenstein says he’s taken a new job to work in higher education nationally. Gov. Josh Shapiro says Greenstein had done an “outstanding job.” Shapiro says he expects the system’s chair to assemble a national search to bring in a new chancellor.
