Introduction
MIE WiSE Program:
•To advance the participation of girls and women in the sciences, engineering, and technology in all areas and at all levels
•Each semester, a select group of women are awarded an educational stipend. These women attend monthly activities that enhance their educational experiences and address issues that face women in the fields of science and engineering
•WiSE participants are actively involved in the Expanding Your Horizons Conference
