Larry Price received the degree of Doctor of Philosophy from Georgia State University in 1997 with concentrations in Research, Measurement, and Statistics and Higher Education. Prior coming to Texas State University, he served as a Psychometrician and Statistician for the Emory University School Medicine, Department of Psychiatry & Behavioral Sciences from 1996 to 1999. Between 1999 and 2001, Dr. Price was employed at The Psychological Corporation in San Antonio, Texas as a Psychometrician II. Dr. Price continues to serve as a consultant for The Psychological Corporation, The University of Texas Health Science Center ­ San Antonio’s Functional MRI Research Imaging Center, and METRICA, Inc./United States Air Force.

My research interests are varied and include:

  1. Theoretical development and testing of Bayesian and non-Bayesian structural equation models in psychological and neuropsychological research.
  2. Theoretical development, testing, and refinement of classical and modern psychometric methods in the behavioral sciences.
  3. Development of dynamic multivariate vector autoregressive time series models for the psychological, social and neurosciences.
