Rachel Herz

Rachel Sarah Herz is both a psychologist and cognitive neuroscientist, and recognized expert on the psychology of smell.


Background

Rachel Herz did an undergraduate degree in Psychology and Biology at Queen’s University in Kingston, Ontario and a MA and Ph.D in the Psychology Department at the University of Toronto. After completing her PhD in 1992, she won a Natural Sciences and Engineering Research Council (NSERC) Post-Doctoral Award and took her research to the University of British Columbia. [1] In 1994, she received the Ajinomoto USA Inaugural Award for Promising Young Scientists and joined the Monell Chemical Senses Center in Philadelphia as an Assistant Member. [2] In 2000, Rachel Herz joined the faculty at Brown University, where she first was a member of the Psychology Department and is now a visiting professor in the Department of Psychiatry and Human Behavior, of Brown University Medical School. Since the mid-1990’s Rachel has been consulting for many of the world’s leading multinational fragrance and flavor companies and regularly lectures to national and international audiences.

In 2004 Rachel changed her relationship with Brown University to more limited involvement so that she could pursue other creative enterprises. It was at this time that she began writing The Scent of Desire: Discovering Our Enigmatic Sense of Smell. (William Morrow/Harper Collins Publishers) as well as working on other means to educate and stimulate the general public about the chemical senses. Her commercial ventures include The Educated Palate and Scentology.

Psychology of smell

Rachel Herz has been conducting research on smell, emotion and cognition for the past 18 years. Her research has shown how odor-evoked memory is emotionally unique compared to other kinds of memory experiences,[3] [4][5] how emotional associations can change odor perception, [6][7] and how odors can be conditioned to emotions and subsequently influence motivated behavior [8] [9]. Her work also deals with how language can affect odor perception and her laboratory has empirically demonstrated the first instance of olfactory illusions created by words alone.[10][11] A third area of her research concerns the role of body-odor and fragrance in heterosexual attraction. [12] [13][14] Theoretically guided by perspectives from cognitive psychology and evolutionary biology, Rachel uses psychophysical, self-report, cognitive-behavioral and neurological techniques, including functional magnetic resonance imaging (fMRI), to investigate these topics.
