Bio
I’m a PhD student in the Quantitative, Qualitative, and Psychometric Methods (QQPM) program in the Department of Educational Psychology at the University of Nebraska-Lincoln. I currently work on new evaluation tools that help make understanding how an intervention’s effects vary based on how well it is implemented (i.e., fidelity to the intervention) easier for educators and researchers. Right now, that means I split my time between consulting at the Nebraska Evaluation and Research (NEAR) Center, developing educational data visualizations, and writing my dissertation. By training, I am a mixed methodologist, data modeler (specializing in latent variable models), and psychometrician; professionally, I’ve worked as a data analyst intern, research consultant, and student director of the NEAR Center.
On this site I keep a technical blog, my CV, and resume. The papers and presentations pages of this site are currently under construction, though many of the titles for these projects can be found below.
