Critical supports and resources within the STEMM research ecosystem are shifting in reaction to rapid changes in institutional, regional, and national environments. In addition, decisions made by external groups and individuals can have a dramatic and profound influence on the well-being, professional development, and interpersonal and mentoring relationships of graduate students, postdoctoral scholars, and faculty. Building upon the conversations held during the first two Roundtable workshops, the goal of this third public workshop is to apply a systemic lens to explore the ways in which individuals, departments and offices, and institutions are addressing and navigating these common challenges.
