I study the effects of aging and stroke damage on the brain, especially with respect to memory and attention. The large numbers of people who will have dementing disorders, stroke, and traumatic damage to the brain lead to an imperative to understand how to protect the brain from these forms of damage and how to mitigate their effects.
In addition, I am interested in the brain basis of perception, especially the neuroscience of the chemical senses- taste and olfaction. The chemical senses are the oldest in evolutionary terms and are tightly linked to the older, limbic parts of the brain in ways that other senses are not. This means that the chemical senses are closely related to our emotions and our memories.
A new area of interest is how a physical structure of space (a building, park, etc.) influences behavior, cognitions and emotion. This area is referred to as Environmental Psychology.
