With respect to causal inference, I develop and apply the principles and practices of (quasi-) experiments that buttress causal inference while paying particular attention to how concomitant social and organizational structures further afford or constrain their feasibility and effectiveness. I also develop statistical adjustments that enable researchers to mount focused, specific analogies of their observational studies to randomized experiments with emphasis on multilevel or clustered settings. In this way, I view statistical methods not as substitutes for random assignment but rather as tools to uncover objective information that will lead to well specified and designed randomized studies.
I also develop and apply explanatory machine learning methods that excel at finding patterns in high dimensional and nonlinear data while also supplying critical explanatory information about the malleable and actionable features that drive outcomes. Methods that can supplement accurate prediction and pattern detection with robust explanations hold foundational value in developing theories and programs because they provide a systematic way to understand, build, test, accumulate and replicate evidence. My work in machine learning is generally situated within multilevel organizational structures where high dimensional, interactive, and nonlinear data are ubiquitous (e.g., classroom teaching).
Similarly, my work on structural equation and latent variable modeling develops methods for complex measurement and nesting structures, high dimensional settings, (approximate) measurement invariance, and nonlinear effects. This work has included, for example, n-level SEM, latent interactions, and structural-after-measurement (SAM) and small sample (nonlinear) estimators and is also generally situated within multidimensional and multilevel contexts (e.g., complex cross-classified assessments of teaching) .
Statistically, these research areas unfold within the context of machine learning methods, (quasi-) experimental design and analysis methods, and latent variable analysis methods. The confluence of these statistical foci take substantive root in understanding the extent to which teacher and school factors can intervene to promote more effective and contextually responsive classroom and school environments. This work has included the measurement and analysis of teachers' knowledge, instructional quality and strategies, and student achievement to identify and explain profiles, pathways and practices (e.g., who teachers are, what teachers know, what teachers believe, perceive and experience, what teachers do) that produce student learning and how these profiles and practices vary across contexts.

Assistant Professor, CECH Educational Studies
Prior to joining the faculty at QMRM at the University of Cincinnati, Youn Seon was an Assistant Professor of Data Science and Biostatistics at the Donald and Barbara Zucker School of Medicine at Hofstra University/Northwell in Hempstead, NY. Youn Seon did postdocs in Prof. Fritz Drasgow’s Psychometric Laboratory at the University of Illinois, Urbana-Champaign, and at BIFIE in Salzburg, Austria. (BIFIE stands for "Bundesinstitut für Bildungsforschung, Innovation & Entwicklung des österreichischen Schulwesens" [Federal Agency for Educational Research, Innovation, and Development of the Austrian Schooling System]—BIFIE is kind of the Austrian equivalent to ETS.)

Vicki L. Plano Clark
Professor, CECH Educational Studies

As a methodologist specializing in mixed methods research, Dr. Plano Clark studies how researchers effectively integrate quantitative and qualitative approaches to address their research questions. Her scholarship focuses on delineating useful designs for conducting mixed methods research, examining procedural issues associated with these designs, and examining larger questions about the contexts for the adoption and use of mixed methods. She has written numerous books and articles in the field of mixed mehtods research. She was the founding Managing Editor for the Journal of Mixed Methods Research and currently serves as an Associate Editor. In 2011, she co-led the development of Best Practices for Mixed Methods in the Health Sciences for NIH's Office of Behavioral and Social Sciences Research. In 2012 she became a founding co-editor of the new Mixed Methods Research Series with Sage Publications. She recently served as Chair of the Mixed Methods Research Special Interest Group of the American Association of Educational Research (AERA).
As an applied research methodologist, Dr. Plano Clark also engages in research and evaluation projects on a wide array of topics such as the management of cancer pain, the identity development of STEM graduate students, the professional development of teachers of Chinese, and the well-being of rural low-income families.
Before joining the University of Cincinnati in 2012, Dr. Plano Clark was the director of the Office of Qualitative and Mixed Methods Research, a service and research unit that provided methodological support for proposal development and funded projects at the University of Nebraska–Lincoln (UNL). She also taught research methods courses in UNL's Educational Psychology department. Prior to that work, she spent 12 years developing innovative curricular materials for introductory physics as UNL's Physics Laboratory Manager.
