Dr. Gottfredson earned her doctorate in Quantiative Psychology from the L.L. Thurstone Psychometric Laboratory at UNC Chapel Hill. Broadly, Dr. Gottfredson applies and extends statistical models used for understanding processes that unfold within individuals over time. She specializes in modeling nested data structures (e.g., multilevel and structural equation models), missing data, mixture models and psychometric measurement. In her applied research, Dr. Gottfredson examines contextual, relational, and person-specific self-regulatory processes that are involved in both the development of addiction and in addiction recovery, and in disordered eating behavior. She is particularly interested in mechanisms which underlie the comorbidity across distinct disorders.
