Project Summary/Abstract This proposed administrative supplement to the Tufts BIRCWH (K12HD092535-06) will be transformative in increasing the diversity of the exceptional researchers in women's health and sex/gender differences with the ultimate goal to better understand basic mechanisms of disease and develop treatment that addresses the heterogeneity of treatment effects by sex. The Tufts University Building Interdisciplinary Research Careers in Women's Health (BIRCWH) Scholars Program was recently renewed to continue a model program to recruit, select, and train early career faculty to conduct basic research in sex/gender differences and clinical and health services research on women's health issues. The long term goals of the Tufts BIRCWH Program are to develop the next generation of leaders in research in sex/gender differences and women’s health. The Program will fund faculty within six years of completing their training. For the additional scholar supported through this administrative supplement, we propose to select from eligible candidates based upon disability or from a group underrepresented in medicine and science who have completed their doctoral training but require more in depth interdisciplinary research training. The Program will achieve its goals through five key activities, tailored to meet each Scholar’s training needs: 1) interdisciplinary mentoring teams, 2) formal research training, 3) interdisciplinary research seminars, 4) a mentored research project, and 5) development of skills in grant proposal preparation. The addition of our BIRCWH DEI Director as part of the parent program will build our existing capacity to advance the recruitment and retention of diverse scientists in the fields of women’s health and sex and gender differences and advance inclusive excellence for all in the program.
