There was an error in the article that appeared in the Sept. 14-21 issue of the Yale Bulletin & Calendar (YB&C) about the appointment of Menachem Elimelech as the Llewellyn West Jones Jr. Professor of Environmental Engineering.
The story incorrectly stated that Elimelech was appointed as an associate professor in 1984. In fact, he was named an associate professor in 1994 and was promoted to a full professorship in 1997. The YB&C regrets the error.
