A Linguistics graduate student has formally charged a senior professor in the department with sexual harassment, according to a letter sent Wednesday by the chairman to members of the department.

The letter from Department Chairman Calvert Watkins said that the University is investigating allegations that Professor of Linguistics Susumo Kuno sexually harassed a female graduate student. The letter was sent to graduate and undergraduate students as well as faculty members in the department.

"As many of you are no doubt aware, a formal charge of sexual harassment has been brought to the appropriate University authorities...against Professor Susumo Kuno. The matter is currently under investigation in accord with University regulations," Watkins' letter states.

"Pending the disposition of the case, and to avoid prejudging an ongoing investigation which lies entirely outside this Department, it would notbe appropriate for me to comment further," theletter continues.
