Research Areas:

Quantitative Psychology & Modelling

Social & Personality

Research Summary:

Are we measuring what we think we are measuring? This is a foundational question for psychological scientists because we often study phenomena that are difficult to observe and measure. I am pursuing two complimentary research trajectories, both aimed at improving measurement practices in psychology. In my quantitative research trajectory, I develop structural equation and multilevel models for measurement, particularly understanding the ramifications of a lack of measurement invariance. In my more applied research trajectory I develop practices, measures, and models for educational and social psychology. A theme in my work is bridging the gap between the quantitative methods and substantive research communities.

I am accepting graduate student applications for the Fall 2019 year (due on December 1st, 2018). To indicate me as a potential advisor, please list my name on the application summary sheet, which is uploaded separately. My name is not listed in the drop-down list in the application portal, but you can still apply to work with me via the application summary sheet.
