After eight years in the job, George Pernsteiner is resigning as Chancellor of the Oregon University System. Matt Donegan, President of the Oregon State Board of Higher Education says Pernsteiner can celebrate many successes but it's time for a change.  Donegan credits Pernsteiner for his work to increase enrollment and improve the public system. He says the next Chancellor will have to take over the monumental task of operating a system that has suffered "years of disinvestment."
