Hand Writing Inscription

Prolepsis was founded by academics in response to increasing constraints placed by universities on the creation of knowledge that matters. We are driven by the desire to generate high-quality, applied scholarship free from restrictive institutional expectations generated by administrators’ growing fealty to ever growing compliance regulations.

We are committed to the pursuit of population health, safety, and wellbeing research with an emphasis on underserved and vulnerable populations and communities. Our work is fueled by our passion for social justice by way of lessening health and safety gaps among and within different populations through effective public policy design, health systems strengthening, and lasting structural changes.

Prolepsis is guided by its mission to have a positive impact on social structures, systems, and policies that can equitably and sustainably enable healthier and safer living and work environments. We aim to achieve this mission by using both traditional and novel research epistemologies and methodologies to provide empirical evidence regarding persistent health and safety challenges and inequities experienced by disadvantaged and vulnerable populations.

Our Vision

Prolepsis envisions a society in which people have a healthier, safer, more productive, and more meaningful working life. Our personal contribution to seeing this unfold is through empirical research, education, and consulting that: (a) fully integrate holistic scientific perspectives, including next-generation science; (b) never compromise rigor and integrity; (c) are always inclusive, innovative, and relevant; and (d) remain anchored in the importance of public and corporate policies as well as the continual strengthening of social and health systems.
