Research

My research interests, broadly defined, are human individual differences. To this end, I have a number of studies underway looking at intelligence and other mental abilities and at normal and abnormal personality. Much of my research involves behavior genetics and I have several ongoing studies of infant and young twins as well as adult twins and adoptees. My research has also looked at a number of biological correlates of human intelligence and my lab has the facilities to continue these investigations. In 1996-1997 I served as Acting President-Elect of the Behavior Genetics Association, and in 2001-2003 I was President of the International Society for the Study of Individual Differences.
