Research Summary

Individuals differ quite substantially in their ability to smell myriad odorants. In some instances a person may not be able to detect an odor when others in the group can clearly perceive it. In other situations all may detect an odor but there is considerable disagreement about what it smells like. I explore this variation at different levels of analyses, e.g., genetic influences, gender differences and the impacts of age and the environment on odor perception. In another area of research I have explored the effects of body odor on the physiology and behavior of individuals who are exposed to the odor. Even among humans there is mounting evidence that we communicate information about ourselves to others via pheromones (chemical communication), often at a subconscious level. This information can be used to identify individuals, to alter hormone systems and to modify mood and emotion.
