Valerie Galluzzi, who received her PhD from the UI Computer Science Department in 2015, has been "Helping Bring Change in Computer Science, One Student at a Time," as written in a Rose-Hulman
Institute of Technology Academic News piece:

"In her first year as a member of the Rose-Hulman faculty, Galluzzi has encouraged the formation of a proposed student organization, Women of Like Fields Passionate About Computing (WOLF PAC), which is striving to get more females to study computer science, computer engineering, software engineering, and electrical engineering on campus. [...]

Galluzzi became interested in computer science while taking an introductory programming class during her senior year in high school in Hawaii. Her educational journey took her across the United States to earn a bachelor’s degree in computer science from Mount Holyoke College (South Hadley, Massachusetts), and a master’s degree and doctorate in computer science from the University of Iowa, specializing in sensor networks and machine learning."
