Diversity, Equity, Inclusion and Accessibility

Activities Promoting Diversity, Equity, Inclusion, Belonging, and Uniqueness:

I started my internship at Boston City Hospital in 1995 with a deep commitment to serve structurally disadvantaged and minoritized communities. I am proud to work at a hospital (Boston City Hospital, now called Boston Medical Center) that promotes exceptional care without exception.

As a health equity researcher, I have recognized the importance of diversity, equity, and inclusion throughout my whole career. Virtually all of my mentees have been women and/or individuals from historically underrepresented groups. As Interim Associate Chief of GIM, in response to glaring racial disparities in the proportion of faculty members promoted to the rank of Associate Professor and Professor at BUSM, I focused on supporting and mentoring faculty historically underrepresented in medicine in the promotions process.

More recently, I have been working with BUSM’s Dean’s Office to undertake a cluster hire of faculty underrepresented in medicine. I have developed a Recruitment Search Protocol to mitigate bias and encourage the recruitment and hiring of faculty identified as women and/or being from underrepresented groups. In developing our recruitment search protocol, I performed a literature review and identified best practices from institutions successful in diversifying their faculty. I also developed a plan to ensure BU’s faculty development programs promote thriving and belonging to ensure retention of new faculty cohort hires. I identified best practices and strategies by reviewing case studies of best practices proven effective at peer institutions; conducting a literature review of barriers to faculty retention; examining faculty experiences at BU; and identifying best practices across BU.

I have also supported diversity, equity, and inclusion nationally, through the Society of General Internal Medicine. I have been a member of the Health Equity Task Force for many years, and have served as the Chair of the Editorial Board of the Journal of General Internal Medicine (JGIM) since May 2021. As Chair, I have initiated discussions with the Editors and Editorial Board about how to make JGIM an anti-racist journal. We have brainstormed about how to diversify the Journal at all levels: authors, Associate Editors, Editorial Board Members, and Editorial team. In my role as Chair, I will lead the Search Committee to identify the next Editorial Team of JGIM. I intend to implement a Recruitment Search Protocol to mitigate bias in the process, and ultimately to hire a more diverse Editorial team.

Academic medicine can be challenging to navigate, particularly for women and individuals from underrepresented groups. With regard to my background, my late father grew up in Bogota, Colombia and was a native Spanish speaker, and much of my family now lives in Peru. Given my background, I am a particularly strong mentor for women and LatinX faculty.
