COLUMBIA UNIVERSITY:
Earth Institute Director Bows Out
Constance Holden
An ambitious attempt to bring scientists from diverse disciplines together to study global problems is about to get fresh leadership. Peter Eisenberger, the controversial director of Columbia University's Earth Institute, resigned on 24 March, citing differences over the institute's direction as well as his health. Columbia has named executive provost Michael Crow, a key force behind the creation of the Earth Institute, as its interim leader until a replacement is found.
