Dr. Beaujean joined the Psychology & Neuroscience department in 2017. Prior to joining, he worked in Baylor's Educational Psychology department where he created and coordinated the quantitative methods specializations for the doctoral and master's programs. In addition, he contributed to the school psychology program and served as the program coordinator for two years where he developed the program's doctoral specialization.

Dr. Beaujean is a prolific scholar, having published 2 books on latent variable models, more than 80 articles and book chapters in peer-reviewed scientific outlets, and presented more than 80 papers/posters at professional conferences. In 2016, he was listed as one of the most prolific faculty members in non-doctoral school psychology programs across the nation, and has won research awards from the American Academy of Health Behavior, American Psychological Association (school psychology division), Mensa Education & Research Foundation, and Society for Applied Multivariate Research. He has been previously awarded funding from the National Institutes of Health, and aided in program evaluations for the National Science Foundation, Inter-American Development Bank, and Lego Foundation. Moreover, multiple organizations and universities have invited him to speak on the issue of data analysis and psychological measurement.

In addition to his scholarship, Dr. Beaujean has extensive experience with psychological assessment in both school and clinical environments. He holds licensure for the independent practice of psychology in Texas. In 2015, his advanced clinical competence was recognized by the American Board of Assessment Psychology when they awarded him a diplomate in Assessment Psychology. In 2020, he was elected President of Division 5 of the American Psychological Association, with his term beginning in 2021.

Academic Interests and Research

Dr. Beaujean's research interests are broadly in the field of individual differences. More specifically, he is interested the application of quantitative methods to study human variability, especially as it relates to cognitive ability and educational outcomes.
