He is Director of the Berkeley Evaluation and Assessment Research (BEAR) Center. His research interests focus on the development and application of sound approaches for measurement in education and the human sciences, the development of statistical models suitable for measurement contexts, the creation of instruments to measure new constructs, and scholarship on the philosophy of measurement. Dr. Wilson received his Ph D degree from the University of Chicago in 1984.  Andrew Maul is a professor of Education at the University of California, Santa Barbara. His work integrates lines of inquiry traditionally associated with statistics, philosophy, psychology, and history, with the aim of improving the quality of methodological practices in the human sciences, and in particular the theory and practice of measurement. Dr. Maul received his Ph.D. in 2008 from the University of California, Berkeley. He regularly teaches courses on the construction and validation of measuring instruments, item response theory, and the philosophy of measurement, as well as introductory and advanced research methods and applied statistics.
