I am an Associate Professor of Quantitative Methods and Director of Research Methods in the Graduate School of Education and Human Development (GSEHD) at The George Washington University. I hold a Ph.D. in Measurement, Statistics, and Evaluation from the University of Maryland, College Park, and a Master's in Assessment, Measurement, and Statistics in Psychological Sciences from James Madison University.
My research centers on methodological issues in latent variable modeling, with a specific focus on data-model fit, structural equation modeling (SEM), and nonlinear modeling. My work has been published in peer-reviewed journals such as Psychological Methods, Educational and Psychological Measurement, Structural Equation Modeling: A Multidisciplinary Journal, the Journal of Experimental Education: Measurement, Statistics, and Research Design, the Journal of Applied Statistical Methods, and Applied Psychological Measurement.
I have over twenty years of experience as a statistical and psychometric consultant, collaborating with clients across diverse fields including audiology, business marketing, education, exercise science, human development, marine biology, medical sciences, neuropsychology, psychology, social work, and student affairs. My clients have ranged from individuals conducting personal research to corporations refining marketing strategies to universities evaluating the effectiveness of general education courses. For four years, I served as the methodologist of Fairfax Neonatal Associate’s PETIT (Prematurity’s Effects on Toddlers, Infants and Teens) study, examining longitudinal neuropsychological, cognitive, and behavioral outcomes in children born prematurely until the study concluded in 2016. My expertise spans a wide range of assessments, including large-scale university assessments, item banking for computer-adaptive tests, instrument and survey design, and small-scale program evaluations.
I teach doctoral courses in quantitative methods including EDUC 8120 (Quantitative Methods), EDUC 8171 (Regression), EDUC 8173 (Structural Equation Modeling), as well as a series of experimental courses such as Data Management I, Data Management II, and Factor Analysis. My courses are offered in a range of formats: traditional face-to-face (F2F), hybrid, and online. Before joining GW, I taught courses in Classroom Assessment and Introductory Statistics at The University of Maryland.

In my free time, I'm a musician with a passion for playing and seeing live music. I love spending time in the mountains, hiking and camping whenever possible. I also enjoy painting, art, DIY projects, and reading fantasy novels.
