PROJECT SUMMARY/ABSTRACT The following is an Administrative Supplement application for Curriculum or Training Modules to Enhance Undergraduate Biomedical Research Training (NOT-GM-22-014) for award number T34GM131948 MARC U*STAR Training Program at the University of Rhode Island. In this administrative supplement application, we describe the design and implementation of a new inclusive graduate student mentoring training program at the University of Rhode Island. This program will promote more effective mentoring in the biological and biomedical sciences through the development of evidence- informed educational and training modules and activities. Specifically, we are requesting funds to send four additional URI faculty and staff from the College of the Environment and Life Sciences (CELS) to the Entering Mentoring Facilitator Training, hosted by the Center for the Improvement of Mentored Experiences in Science (CIMER) at the University of Wisconsin- Madison. Facilitating Entering Mentoring is a two-day “train-the-trainer” workshop designed to increase the capacity for research mentor trainings offered at colleges and universities, research institutes, and governmental organizations. Following completion of NRMN Mentoring Facilitator Training, MARC team members will design and develop a 3-4 module graduate student inclusive mentoring training program that allow participants to delve more deeply into the various components of inclusive mentoring practices and roles as graduate mentors in research environments. The objectives of these modules will be to: (1) Cultivate awareness among graduate mentors on the need for inclusive approaches; (2) Provide strategies for cultivating sustained dialogue between graduate mentors and undergraduate mentees; and (3) Support graduate research mentors in the development of their own inclusive mentoring.
