About Jennifer

Cossyleon's research focuses on community, labor, and the transformative effects of local social movements through community-engaged and policy-informing methods. Overarching themes in Cossyleon's writings include how mothers of color and returning citizens contest marginalization through collective action, how housing and criminal justice policies contour the lives of the most oppressed groups, and how kinship is embedded and constructed through mobilization. Recent research is related to the intergenerational effects of community organizing, the economic impacts of immigration enforcement on the economy, and the experiences of dairy workers in Central Valley, CA amid a bird flu outbreak.

Publications

"The Effects of Recent Federal Immigration Enforcement on Private Sector Employment in California and Washington, D.C." (with Edward O. Flores and Keila Luna Monterrey), University of California, Merced Community and Labor Center, December 2025.

Analyzes Current Population Survey data before and following escalations in federal immigration enforcement actions in California and Washington, D.C. The effect of escalated immigration enforcement actions on work is comparable with the Great Recession and the onset of the COVID-19 pandemic. Ongoing escalated immigration enforcement actions suggest the need for policy interventions to mitigate negative economic consequences.

"The South Central Valley Community Needs Assessment: Labor, the Environment, and Civic Action" (with Paul Almeida), University of California, Merced Community and Labor Center, October 2025.

Provides a snapshot of the unmet needs of south Central Valley workers and families on the frontlines of an economic and environmental crisis, as well as their desire to participate in civic action.

"Producing Risks: Dairy Workers’ Experiences and the Need for Worker-Centered Bird Flu Mitigation/ Produciendo Riesgos: Experiencias de Trabajadores Lecheros y La Necesidad de Mitigación de Influenza Aviar Centrada en los Trabajadores" (with Edward O. Flores, Rodrigo Alatriste-Diaz, Andres Arias, Karina Juarez, and and Keila Luna Monterrey), University of California, Merced Community and Labor Center, February 2025.

Uses neighborhood and convenience sampling methods to interview dairy workers employed in nine cities within Kings, Fresno, Tulare, and Merced counties. Interviews with workers underscored the nature of non-compliant sanitary practices, the prioritization of production over worker health, and how the lack of an economic safety net shapes workers’ responses to health and safety practices.

"Producing Risks: Dairy Workers’ Experiences and the Need for Worker-Centered Bird Flu Mitigation" (with Edward Flores, Rodrigo Alatriste-Diaz, Andres Arias, Karina Juarez, and Keila Luna Monterrey), University of California, Merced, February 2025.

Looks at how dairy workers actually experience bird flu risk on the job, focusing on their day-to-day working conditions and the gaps in safety protections. Finds that current prevention efforts often overlook workers’ realities—like limited training, inconsistent access to protective gear, and fear of speaking up—and argues that solutions need to be designed around workers’ needs and voices to be effective.

"The Effects of Recent Federal Immigration Enforcement on Private Sector Employment in California and Washington, D.C." (with Edward Orozco Flores and Keila Luna Monterrey), University of California, Merced, December 2025.

Looks at how recent increases in federal immigration enforcement affected jobs in places like California and Washington, D.C., by tracking changes in employment over time. Finds that when enforcement ramps up, fewer people—especially noncitizens—report working, leading to noticeable drops in private-sector employment and broader negative effects on local economies.

"The South Central Valley Community Needs Assessment: Labor, the Environment, and Civic Action." (with Paul Almeida), University of California, Merced, Forthcoming.

Provides a snapshot of the unmet needs of South Central Valley workers and families on the frontlines of an economic and environmental crisis, as well as their desire to participate in civic action.

lluminates how collective action shapes the kinship relationships of women of color leading a local restorative justice movement in Chicago Uses forty-seven in-depth interviews with community organizers and fifteen months of participant observations of local collective action as evidence, I highlight the intersecting processes of collective action and family life. Findings elucidate how leaders in the study, most of whom were African American and Latina mothers and grandmothers, coproduced com-munity organizing and family life. 

"Racial Discrimination in Housing: How Landlords Use Algorithms and Home Visits to Screen Tenants" (with Eva Rosen and Phillip M.E. Garboden). American Sociological Review (2021).

Studies how such discrimination operates, and the intermediaries who engage in it: landlords. Discusses how a fundamental assumption of racial discrimination research is that gatekeepers such as landlords are confronted with a racially heterogeneous applicant pool.

"Collaborating then Stepping Back: Roles for Community Organizers and Researchers in Participatory Action Research" (with Gina Spitz) in Routledge International Handbook on Public Sociology, edited by Leslie Hossfeld, E. Brooke Kelly and Cassius Hossfeld, (Routledge, 2021).

Documents how researchers and members of a nonprofit community organizing institution collaborated on a survey to understand debt, including the types, the amount, and the social consequences of debt, for economically marginalized communities of color in Chicago. Begins with the goal of impacting state and city-level policy, this Participatory Action Research built on the strengths of community members and researchers to develop research questions and survey instruments, formulate an implementation plan, and summarize results.

"'Power in Numbers': Marginalized Mothers Contesting Individualization through Grassroots Community Organizing" in Advances in Gender Research, edited by Marcia Texler Segal, Kristy Kelly, and Vasilikie Demos, (Emerald Group Publishing Limited, 2019).

Notes much philanthropic and academic interests focuses on the quantifiable outcomes and impacts of collective action. Turns inward to the experiences of local social movement participants, Black and immigrant Latina mothers in Chicago. Illuminates how marginalized mothers of color contest the individualization of social problems through grassroots community organizing, gaining collective purpose and voice through the process and how we must rethink our narrow measures of movement "success."

"'Coming Out of My Shell': Motherleaders Contesting Fear, Vulnerability, and Despair through Family-focused Community Organizing" Socius: Sociological Research for a Dynamic World 4 (January 2018).

Examines African American and Latina low-income mothers involved in local family-focused community organizing, called "motherleaders." Finds their engagement transformed their everyday lives, perceptions, and relationships. Finds motherleaders' personal narratives highlight how their experiences and understandings of community organizing are inseparable from their intersecting identities and how this type of civic engagement has the propensity to alter the lives of marginalized groups far beyond the publicly stated goals of organizations.
