University of Arizona President Ann Weaver Hart, on campus one week, outlines an aggressive agenda for maintaining and expanding the school's place in the hierarchy of great universities.

In an extensive interview, Hart notes that the UA is ranked 50th internationally in research and says she will work to keep it there and make improvements in the face of challenging times for higher education.

Those challenges are especially daunting for public universities, Hart says, with continued pressure from state legislatures leading to searches for other funding sources.

More public-private partnerships, technology transfers and other creative financing means will be needed to keep public universities viable in the face of reduced state funding, Hart says.
