Research
Research
My research focuses on the development and application of advanced modeling and data mining approaches for the analysis of complex psychological data, and considers ways in which various substantive domains within psychology can be studied through these analytic approaches. I have developed and utilized data mining techniques to fit optimal structural equation and longitudinal models. In addition to data mining techniques, another aspect of my research is in estimation issues within structural equation modeling (SEM). I am also particularly interested in applying modeling techniques to study developmental processes, with an emphasis on economically disadvantaged immigrant children. My collaborative work with applied researchers in the Minnesota Population Center recently received 5-years of funding from the National Institute of Health to investigate the complex associations among parenting, marginalization, and well-being during the COVID-19 pandemic.

Teaching
Teaching
I teach undergraduate and graduate quantitative courses at the University of Minnesota, including Honors Introduction to Psychological Measurement and Data Analysis, Structural Equation Modeling for the Social and Behavioral Sciences, and Multilevel Modeling for Psychological Data. At the University of Florida I taught graduate courses in Regression Analysis, Data Mining, Multilevel Modeling, and Structural Equation Modeling. I have taught an Introduction to Educational Data Mining workshop at the Florida Educational Research Association (FERA) annual conference. I have also previously assisted and presented at the APA Advanced Training Institute workshops on Big Data: Exploratory Data Mining in Behavioral Research and Structural Equation Modeling in Longitudinal Research.
