I obtained a B.S. Degree in Psychology and a B.S. in Economics from Purdue University in 2017. I am pursuing an M.S. in Psychological Science at the University of Illinois at Urbana-Champaign, where I study with Dr. Daniel Newman and his team about psychometrics.

Research Description

My research aims to evaluate the fit of certain measurement models for latent traits. In particular, I am interested in using Item Response Theory (IRT) and Classic Test Theory (CCT) to evaluate equity sensitivity. Traditionally, equity sensitivity represents the ratio of one’s preferred outputs to inputs in a work environment. Jeon and Newman (2015) proposed a more intuitive definition of equity sensitivity as a dispositional tendency to perceive stimuli as fair versus unfair, and they created a Neutral Object Fairness Orientation (NOFO) measure to evaluate their new definition of equity sensitivity. Inspired by this work, I am interested in evaluating equity sensitivity using an ideal point model. Improving the validity of the NOFO measure could improve understanding of individual differences in perceived fairness.
