Tracy's PhD thesis established that a simple technique (i.e., a self-affirmation manipulation) that encouraged people to reflect on salient positive aspects of their self (e.g., by writing about their values) could be used in conjunction with health risk information to change health behaviour.

Following her PhD Tracy worked on a number of research projects.
