Luke is a personality psychologist. His research interests broadly relate to the causes and consequences of major personality traits. Much of his work concerns the relation that personality has to emotion/motivation, with a large proportion of this work focusing on the trait domain called Extraversion. He is also interested in testing and refining theories concerning biological mechanisms that may underlie personality differences (including those that mediate the effects of social/environmental influences on personality), and in neuroscience paradigms that can serve this goal. -Blurb taken from unimelb.edu
