I am a medical sociologist with research and teaching interests in racial health disparities, political and policy determinants of health, LGBT health, critical race theory and racism, and racial and ethnic relations. My previous work has been published in Sociology of Race and EthnicityJournal of Immigrant and Minority Health, and Gender in Management: An International Journal.

I received a B.A. in Political Science and Africana Studies and a Ph.D. in Sociology with concentrations in health disparities and race and ethnicity from Texas A&M University.  I am currently an Assistant Professor at Mississippi State University in the Department of Sociology and the African American Studies Program.  

Racism, homophobia, and transphobia diminish the health of people of color and LGBT individuals through structural mechanisms of inequality, discrimination, stigmatization, and minority stress.

My research lies at the intersection of medical sociology, sociology of race and ethnicity, and political sociology.  Theoretically, I argue that research in the social determinants of health have largely overlooked the impact of political and policy factors in health outcomes and that political epidemiology should be prioritized in the study of health.  

My overarching goals are to investigate the mechanisms and implications of intersecting modes of social inequality and stratification.  In particular, I am interested in the health of sexual and gender minorities and how racism intersects with homophobia and transphobia to present health inequities for sexual and gender minorities.


LGBT-Protective Policy

Using a novel dataset with more than 40 state-level LGBT-protective policy measures  related to parenting and relationships, hate crimes and criminal justice, non-discrimination, religion, school and youth, and health and safety, I examine the impact of state-level policy on individual and aggregate health outcomes, including HIV/AIDS, mental health, physical health, health access, and health behaviors.  

The Survey on Intersectional Health Disparities examines how the health status of LGBT adults varies by sexual orientation/gender identity, racial/ethnic identity, and the intersections of these identities.

COVID-19 Dating Project

 Early interviews during the COVID-19 pandemic suggested four frames for dealing with risk associated with COVID-19 while dating: 1) Unconcern About Risk; 2) Preliminary Risk Assessment; 3) Active Risk Negotiation; and 4) Risk Averse (Williams, Miller, and Marquez-Velarde 2021).  Our current research analyzes survey data from over 1,000 respondents related to dating behaviors and COVID-19 risk.

We assess the likelihood of moderate and severe psychological distress among Black immigrants. We test the region of context framework, which states that Black immigrants from majority-Black and racially mixed regions of origin have better health outcomes than Black immigrants from majority-white contexts. We utilize data from IPUMS Health Surveys, 2000–2018. We employed partial proportional odds models to assess the likelihood of moderate and severe psychological distress among Black immigrants and U.S.-born Black Americans. All immigrant groups, except for Black Europeans, are significantly less likely to be in moderate and severe distress vis-à-vis U.S.-born Black Americans (p < 0.01). Black Africans are about 54–58% less likely to be in severe distressed compared to U.S.-born Black Americans. Black immigrants from racially mixed and majority-Black contexts (Mexico, Central America, Caribbean, South America, and Africa) are significantly less likely to be afflicted with moderate and severe distress than U.S.-born Black Americans.
