It is well-documented that exposure to stigma is robustly associated with negative health outcomes and is proposed as a fundamental cause of mental health disparities between stigmatized (e.g., LGBTQ+) and non-stigmatized populations. Extending this body of work, researchers have begun to propose mechanistic pathways linking stigma and mental health. For example, one way that stigma-related stress affects mental health is by disrupting interpersonal relationships, leading to adverse interpersonal outcomes (e.g., loneliness). Despite growing evidence for this pathway, a limited body of research has: 1) conceptualized and tested the multitude of biopsychosocial mechanisms through which stigma causes adverse interpersonal outcomes; and 2) incorporated the effects of “up-stream” macro-social contextual influences (e.g., structural stigma—“societal-level conditions, cultural norms, and institutional policies that constrain the opportunities, resources, and well-being of the stigmatized”).  As a result, the field lacks a comprehensive understanding of the various ways in which stigma—operating across multiple levels of influence (i.e., structural, interpersonal, and individual)—indirectly interferes with interpersonal relationships in ways that increase risk for poor mental health. The central objective of Micah’s research program is to address this gap in the literature by testing direct and mediating pathways linking stigma operating at multiple levels to relationally-oriented mechanisms, adverse interpersonal outcomes, and mental health.

Micah received his Ph.D. in Social Psychology from Duke University. As a postdoctoral fellow, he completed the Columbia University Mailman School of Public Health Psychiatric Epidemiology Training Program. He subsequently continued his postdoctoral training within the Department of Psychology at Harvard University.
