About Me

I earned my Ph.D. in Educational Psychology with a Specialization in Measurement, Statistics, and Methodological Studies at Arizona State University. My research interests broadly include:

  • educational and psychological measurement (multidimensional) item response theory, multi-stage testing
  • dimensionality assessment
  • differential item functioning and measurement invariance
  • psychometric modeling, including Bayesian and cognitive diagnostic models

I teach courses in Intermediate Statistics Applied to Education (both face-to-face and online), Educational Assessment and Psychological Measurement, Psychometric Theory, and Advanced Measurement.

In addition to my research on the topics above, I mentor graduate students in related topics related within the field of measurement, such as cognitive diagnostic modeling, longitudinal measurement invariance, dimensionality assessment, and item response theory. Example advisee project topics/titles include When do subscores add value?; Investigation and treatment of missing data in application of cognitive diagnostic models; Examining the Robustness of the Latent Growth Curve Model to Violations of Longitudinal Measurement Equivalence, and Examining Cognitive Diagnostic Modeling in Small Sample Contexts to name a few.

I also lead a weekly research group open to students with methodological research interests in which I mentor graduate students of all stages. Sample collaborative projects emerging from this research group include published papers (e.g., “Examining DIF in the context of CDMs when the Q-matrix is Misspecified”; “Recovery of parameters in multidimensional item response theory models under complexity and nonormality”) and numerous national conference presentations.

Note: I am currently accepting doctoral students in Inquiry Methodology, quantitative track. Students with research interests that align with mine are encouraged to apply, including students whose research interests fit broadly under the umbrella of the topics above.
