Spring Semester 2023 Speakers

Friday, February 24, 12:00pm – 1:00pm: Paul Wesson, Assistant Professor of Epidemiology and Biostatistics, University of California, San Francisco

Title: Epidemiologic applications of Capture-Recapture to sample hard-to-reach populations and generate prevalence estimates: Principles, Limitations, and New Horizons.

Dr. Paul Wesson

Dr. Paul Wesson is an epidemiologist focused on quantifying the health burdens of (and disparities related to) hard-to-reach and socially marginalized populations, particularly as they relate to infectious diseases. His research expertise includes developing and using data driven methods for sampling hard-to-reach and “hidden” populations, population size estimation methods, and using advanced epidemiologic and statistical techniques to study the social determinants of health. He sees his research as existing at the nexus of infectious disease, data science, and social epidemiology; as such, he incorporates theories and principles from social epidemiology to inform and guide his study designs and analyses (e.g. intersectionality, minority stress theory).

As an HIV researcher, his focus is on the unique challenges of sampling hard-to-reach populations for HIV surveillance. He leverages information from the sampling process (and survey data) to generate estimates of the population size. Valid estimates of the population size inform how and where limited public health resources should be targeted. Dr. Wesson has also developed novel population size estimation methods to correct for known biases. In future work Dr. Wesson plans to extend to geo-spatial analysis and clinical data to further examine contextual and structural determinants of disparities in health outcomes.

Friday, March 10, 12:00pm – 1:00pm: Dr. Stephen Gavazzi, Director, Center for Human Resource Research (CHRR)

Title: Data and Samples Available Through CHRR at The Ohio State University: The National Longitudinal Studies, Ohio Longitudinal Data Archive, and the American Population Panel

Dr. Stephen Gavazzi

Stephen M. Gavazzi, Ph.D. is Director of CHRR at The Ohio State University, as well as a professor in the College of Education and Human Ecology at Ohio State. Dr. Gavazzi is responsible for the overall operations of CHRR, which serves as Ohio State’s center for data and survey excellence. His areas of expertise include a variety of topics within human development and family science (he is a trained marriage and family therapist), with a special emphasis on matters concerning families with adolescents. Professor Gavazzi also has a strong interest in issues surrounding higher education, including leadership, campus-community relationships, and the mission of land-grant universities. His latest book (What’s Public About Public Higher Ed? published in 2021 by Johns Hopkins University Press) was based on survey data collected using CHRR’s American Population Panel.

Friday, April 21, 12:00 pm – 1:00 pm: Dr. Nicholas Bowman, Director, Center for Research on Undergraduate Education

Title: University Rankings Systems and Their Effects on Admissions Indicators and Reputation

Dr. Nicholas Bowman

Nicholas A. Bowman is the Mary Louise Petersen Chair in Higher Education, professor in the Department of Educational Policy and Leadership Studies, senior research fellow in the Public Policy Center, and director of the Center for Research on Undergraduate Education at the University of Iowa. His scholarship uses a social psychological lens to explore key topics in higher education, including student success, diversity and equity, rankings, admissions, and quantitative methodology. Bowman’s work has appeared (or is currently in press) in 100 peer-reviewed journal articles, over 25 book chapters, and nearly 150 peer-reviewed conference presentations. This research has been published in outlets such as Review of Educational Research, Educational Researcher, Sociology of Education, Social Psychological and Personality Science, and Science Advances. Bowman received the Promising Scholar/Early Career Award from the Association for the Study of Higher Education in 2012, and he was the University of Iowa Scholar of the Year in 2018.
