Ezekiel Dixon-Román, PhD

Dr. Dixon-Román’s research rethinks and reconceptualizes the use of quantitative methods from a critical theoretical lens (broadly conceived), particularly for the study of social reproduction in human learning and development.

Dr. Dixon-Román’s theoretical and empirical work has demonstrated alternative possibilitiesvia three primary and interrelated areas of inquiry:

  • inheritance and the social reproduction of “difference” (e.g., race, gender, class, sexuality, and dis/ability) in education, with a particular focus on theoretically and empirically demonstrating alternative ontological and epistemological approaches to social inquiry;
  • the production of knowledge with the methods of quantification, with a particular focus on rethinking and reconceptualizing their ontological and epistemological assumptions and practices;
  • critical inquiry on social policies that seek to address issues of inequality, social mobility, and education.

Dr. Dixon-Román co-edited Thinking Comprehensively About Education: Spaces of Educative Possibility and Their Implications for Public Policy (Routledge) and is the author of the forthcoming Inheriting ImPossibility: New Materialisms, Quantitative Inquiry, and Social Reproduction in Education (University of Minnesota Press). He is currently working on two book projects: Handbook of Critical Inquiry and Quantitative Methods and Measurement, Data, & Society.

Malitta Engstrom, PhD

Dr. Malitta Engstrom is an assistant professor in the School of Social Policy & Practice. Her research focuses on problematic substance use and its co-occurrence with victimization, HIV, incarceration and mental health concerns, particularly as they affect women and families; multigenerational social work practice with families; and grandparents caring for grandchildren. Her scholarship aims to disentangle complex relationships between substance use and co-occurring concerns and to inform innovative, evidence-supported services for individuals and families. With competitive funding from the National Institute on Drug Abuse and the John A. Hartford Foundation, Dr. Engstrom’s current research includes the design and pilot-test of family-oriented services with grandmothers and mothers affected by maternal substance use problems and incarceration. Her emerging work also evaluates a SAMHSA-funded HIV and substance abuse prevention program serving African American women and examines substance use and co-occurring concerns as they affect older women.

Antonio Garcia, MSW, PhD

Dr. Antonio Garcia joined the School of Social Policy & Practice at the University of Pennsylvania as an assistant professor in 2012. His research trajectory is informed and enriched by his wealth of experience as a former Child Protective Services Worker and Supervisor in Washington State. Since earning his doctoral degree in Social Welfare at the University of Washington in 2010, his research and publication record has focused on understanding epidemiological trends related to children of color’s experiences in foster care; and etiological explanations for their increased risk of out-of-home displacement, and lack of access to and use of effective mental health interventions as compared to their Caucasian counterparts. Additionally, his post-doc training at the Child and Adolescent Services Research Center in San Diego, CA between focused on identifying how to shrink the research to practice gap to ameliorate these disparities.

TJ Ghose
Toorjo Ghose, PhD, MSW

Dr. Ghose focuses on structural interventions in the area of substance abuse, homelessness and HIV, both at the domestic and international levels. His research examines the manner in which contextual factors such as housing, community mobilization and organizational characteristics influence substance use and HIV risk. He is currently working with community-based agencies in New York city to study the effectiveness of providing housing as an intervention for substance-using women with HIV released from prisons and jails. A second project involves a collaboration with scholars at the Treatment Research Institute in Philadelphia, state substance abuse agencies in the U.S. and addiction treatment centers to examine the effects of facility-level financial interventions in treatment effectiveness. Dr. Ghose also works with collectives of sex workers and transgendered people with HIV in India, New York and Philadelphia to examine the effectiveness of social movement mobilization in reducing HIV risk.

Johanna Greeson, PhD, MSS, MLSP

Dr. Johanna Greeson is passionate about reforming the child welfare system, using research to build better futures for youth who age out of foster care, and realizing the power of connections to caring adults for all vulnerable youth. Her research agenda is resiliency-focused and based in the strengths and virtues that enable foster youth to not only survive, but thrive. Dr. Greeson’s published work includes scholarly articles on natural mentoring, evidence-based practices for older youth in foster care, including independent living programming, residential group care, intensive in-home therapy, low-income homeownership, and child/adolescent traumatic stress. During her doctoral training at the University of North Carolina at Chapel Hill, Dr. Greeson developed an affinity for research methods, advanced statistical modeling, and collaborative multidisciplinary research with a number of peers and leaders in her field. Her work on various research projects integrated the disciplines of social work, sociology, public health, advanced statistics, and economics and community development, and provided her with fluencies that allow diverse collaboration and competencies to launch a productive program of research. Of particular note, during her course work she developed a theory- and research-based intervention for older foster youth, Caring Adults ‘R’ Everywhere (C.A.R.E.), intended to solve the aging out dilemma.

Dr. Hillier is a Senior Fellow at the Leonard Davis Institute of Health Economics and Center for Public Health Initiatives.

Roberta Rehner Iversen, PhD, MSS

Dr. Roberta Iversen uses ethnographic research to better understand and improve welfare and workforce development policy and programs and to extend knowledge about economic mobility, especially in relation to families who are working but still poor. Dr. Iversen’s ethnographic accounts illuminate what low-income working parents need from secondary schools, job training organizations, businesses and firms, their children’s public schools, and public policy in order to earn enough to support their families through work. Housing policy in Milwaukee, WI, and workforce development programs and policy in New Orleans, LA, Seattle, WA, St. Louis, MO, and Philadelphia, PA, have been improved by findings from Dr. Iversen’s research. Dr. Iversen’s earlier book, Jobs Aren’t Enough: Toward a New Economic Mobility for Low-Income Families (2006; Temple University Press) presents new ways to increase the economic mobility of low-income families.
