This three-study dissertation explored: "How are higher education stakeholders radically (re)imagining liberatory, abolitionist, decolonizing, and queering futures within U.S. higher education and beyond?" With diverse cohorts of Collaborators, I examined this question through a bricolage methodology (Hammersley, 2008), which blended the traditions of critical arts-based methods (Finley, 2011), critical participatory action research (Fine & Torre, 2021), interactive interviews (Ellis, 2008) and focus groups (C. S. Davis & Ellis, 2008), and case study methods. Through this bricolage approach, we engaged in a praxis (Freire, 1968/2005; hooks, 1994) of radical imagination (reflection) and critical creativity (action) through which the following findings emerged. First, radical imagination and critical creativity (RICC) praxis is an ontoepistemological process of becoming, which is accessible to anyone, pluralistically embodied, and situationally located within our broader intersecting sociopolitical and ecological contexts. Second, RICC praxis is necessarily collectivistic, both engaged across intersecting communities and experienced as a continuum from our ancestors to future generations. Third, to promote and sustain individual, community, and ecological flourishing through RICC praxis, we must prioritize holistic, mutual well-being and inter/intrapersonal trauma-informed healing. Finally, RICC praxis is an ongoing process (not a "one size" blueprint) for dismantling "what is" while simultaneously radically imagining and critically creating "what can be." I catalyzed these findings to evolve the conceptual framework that guided this study (i.e., RICC praxis) into an emergent model: "Becoming CRITICAL CREATIVES" (Collective Radical Imaginaries Transforming Interdisciplinary Creativity [to] Advance Liberation [by] Co-constructing Reflexive Ecologies for Abolitionist, Trans*/queering, [and] Indigenizing Vocations Engaged Sustainably). The "Becoming CRITICAL CREATIVES" model centers pluralistically embodied people and their intersecting community/environmental continua. Individuals/collectives/ecologies are wrapped in multidimensional well-being for trauma-informed healing, which is both supported by and sustains ongoing engagement in RICC praxis to collectively engender liberatory, abolitionist, decolonizing/Indigenizing, and queering/Trans* futures. RICC praxis cyclically catalyzes transgressive, everyday outcomes through small actions that cumulatively affect larger scale transformative change. This process necessarily rests on a holographic (Meyer, 2013) onto-epistemological foundation that honors and embraces the intertwined knowing, doing, and being of mind, body, and spirit: Each part of the "Becoming CRITICAL CREATIVES" model co-in/forms each other part "and" likewise the wholeness of the model is contained "within" each part in inseparable measure.
