Professor Delroy L. Paulhus, Ph.D. has taught at the University of British Columbia for 30 years, interrupted only by sabbaticals at UC Berkeley and UC Davis. Del received his undergraduate degree from Carleton University and his graduate degrees from Columbia University.

As the publisher of 150 books, chapters, and articles and as an associate editor for several journals, Del has contributed widely to the fields of social and personality psychology.  His extensive work developing a taxonomy of socially aversive characters – including narcissism, Machiavellianism, and sadism – led him to develop a number of questionnaires, including the Short Dark Tetrad (SD4).

In addition, his long-time interest in self-presentation has spanned socially desirable responding, self-deception, and impression management both inside and outside the laboratory.  He continues to conduct research on a variety of topics related to dark personalities and self-presentation.
