Like every other college and university in the country -- probably the world -- Greenback is pinching pennies. Hard. Discretionary purchases are out, deferrable maintenance is deferred, raises are even more illusory than usual. Hiring is generally frozen ( de facto if not de jure), but there are a few exceptions. Filling key faculty vacancies is one of them. And Greenback's lack of a professor of sustainable engineering is considered a key vacancy.
