His interests in behavioral genetics began as an undergraduate majoring in psychology, where he became fascinated by Hans Eyesenck’s research on the genetics of personality. This interest led him to pursue a PhD in behavior genetics at University of Queensland, working with Dr. Nick Martin. Upon completing his degree, he moved to the United States for what was supposed to be a 2-year post-doctoral fellowship at the Virginia Institute for Psychiatric and Behavioral Genetics, as he felt that VIPBG was the best place to obtain advanced training in structural equation modeling and for learning methods involving both twin designs and molecular genetics. Thirteen years later, he is still at VIPBG, “married and living the American dream,” as he likes to put it.
