Jayhawks Breaking Barriers (JBB) started as a spring 2017 semester-long project at the University of Kansas organized by graduate and postdoctoral students and funded by the American Association of University Women (AAUW). This initial project aimed to increase awareness of the gender leadership gap in STEM, empower women through leadership and mentoring opportunities, and foster discussion about the gender leadership gap among university women and the community. Moving forward, JBB decided to translate the workshops and skills from the spring 2017 project into a formal course taught at KU, expanding the content cover to include all underrepresented groups and their allies in STEMM fields. Through partnerships with the College of Liberal Arts & Science and the Department of Ecology and Evolutionary Biology, STEM Professional Development was offered for the first time in Fall 2018, and is currently being offered this Fall 2019. Furthermore, the Emily Taylor Center for Women & Gender Equity partnered with JBB to create the KU-WiSTEMM Mentoring Program for undergraduate and graduate women in STEMM fields at KU.
