He completed his doctoral training in Quantitative Psychology at the University of California, Davis under the guidance of Dr. Emilio Ferrer and Dr. Kevin J. Grimm. His current program of research is focused on the development and application of statistical models for longitudinal research in psychology and other social sciences. He is especially interested in the lack of coherence between nomothetic and idiographic approaches to research, and its implications for methods used to measure and analyze psychological phenomena. Some of Gonzales's more substantive interests relate to topics in evolutionary psychology, especially with respect to sex differences, intimate relationships, and hormones and behavior.
