Many barriers have prevented women from advancing in academic STEM careers, especially women of color. Few studies have focused on the career paths of Latina STEM scholars and challenges they face as both women and as members of an ethnic minority group. We are investigating the career paths of former Latina UC President Postdoctoral fellows in various STEM disciplines by conducting in-depth, semi-structured interviews. The interviews are designed to identify the social, familial, and institutional barriers scholars have faced, their experiences of gender, class, and ethnic/racial discrimination, and the impact of the fellowship on their career success. Our paper highlights the importance of the creation of a scientist identity among Latinas through the use of culturally appropriate and sensitive mentoring.
