Both took place on campus Saturday night. Police say a man on a bike groped a woman around 7 p.m. outside the event and recreation center. The second attack happened about 9:20 p.m. near the Hoover Hall dorm.
Witnesses say the attacker was a white man in his 20s with a mustache, wearing a black hoodie and pants. He left the scene of both incidents riding on a bicycle.
Many students learned about the assaults through text messages sent by the university.
Students are encouraged to call for a campus police escort at night.
The victims, who are students, were not harmed.
