About

Chelsea Song

Q. Chelsea Song
My research focuses primarily on three topics:
  1. Enhancing diversity in the workplace
  2. Person-environment fit and longitudinal development of personality and vocational interests
  3. Research methods
These topics aim to answer questions evolving around personnel selection (e.g., hiring, promotion) such as what predicts workplace outcome (e.g., personality, vocational interests), how to measure them (e.g., psychometrics), and how to make decisions (e.g., diversity in hiring, multiple-objective optimization). My work implements various methods, such as multilevel modeling, longitudinal models, meta-analysis, Monte-Carlo simulation, and I am also particularly interested in studying the application of machine learning and Big Data methods in hiring practices.

My list of research interests are as follows:
  • Diversity in HR (enhancing race & gender diversity via hiring; adverse impact reduction)
  • Vocational interests, Personality development, and Person-environment fit
  • Research methods (machine learning / Big Data, multilevel & longitudinal models, measurement / item response theory)
