Equity in STEM

The Call Laboratory and its members recognize the lack of representation of black, indigenous, people of color, LGBTQ, and other minority groups in STEM careers, graduate programs, and positions of power. As a single lab, we may not be able to change the systemic foundations that have created this deficit and prolong its existence. We are committed to actively promoting diversification and equity in STEM, in whatever way we can. Toward that goal, our laboratory pledges to: 

  1. Listen to the thoughts and concerns of underrepresented classes and make actionable plans to address these concerns
  2. Understand and fight against the structures perpetuating inequality in our local STEM community
  3. Foster supportive research and mentoring environment for graduate and undergraduate student researchers of color and diverse backgrounds
  4. Provide research opportunities to individuals of underrepresented communities who may otherwise not have access to these career-building/advancement opportunities
  5. Work with Athens community leaders to identify and deconstruct barriers limiting STEM as a viable career option for students of color
STEM and Social Resources

The Office of Recruitment and Diversity Initiatives at the University of Georgia strives to promote academic excellence by recruiting students from diverse, underrepresented backgrounds and provide support to these students throughout their graduate career. The Graduate School encourages enrollment of underrepresented minorities, including those race/ethnicity, gender within discipline, first generation, non-traditional age and/or a self-identified aspect of a uniquely diverse background.

The PREP Program at the University of Georgia offers a one-year, full-time, intensive research training experience designed to prepare post-bachelor students for graduate training and a successful career in science. This experience will help round out an individual’s skillset in the areas of oral, written, and graphic communication and make them more competitive for MS, PhD, MD, and other professional and higher education programs.

The Peach State LSAMP is dedicated to increasing the number of underrepresented minorities in bachelor’s programs in STEM, as well as encourage the pursuit of graduate-level studies in these fields. The alliance provides peer and faculty mentoring, tutoring and advising, high school mentoring, as well as summer research opportunities to individuals of underserved communities.

#SHUTDOWNSTEM and #SHUTDOWNACADEMIA is STEM professional-driven initiative to push for advocacy for Black lives. Academia and the STEM fields have benefitted and played into the structures that perpetuate racial inequality. #SHUTDOWNSTEM is devoted to dismantling anti-black racism in the academy and supporting the success of underrepresented minorities in the field.

The Athens Anti-Discriminations Movements (AADM) is devoted to advocating for social and racial justice and fighting racial injustice through the use of educational resources and local activism. Their mission is to ensure fair treatment of people of all races, raise awareness, and advocate against systemic practices used to repress or infringe on the rights of an individual or group.
