Research Description:

The olfactory system does two unique things: It detects odors and it replaces injured neurons by activating resident tissue-level stem cells, even in adults. My lab investigates the molecular physiology of both of these processes, but current emphases are on the function and pharmacology of the odorant receptors.

Odorant receptors comprise the largest gene family in mammals, with up to nearly 2,000 genes in some species. Every odor is thought to activate a small subset of these receptors, and because each olfactory sensory neuron expresses only one odorant receptor gene the pattern of receptor responses exactly determines the pattern of information the brain must use to perceive and discriminate odors. We invented a way to identify these receptor response patterns in vivo and are using it to investigate what patterns arise, how they overlap, whether odorants interact at the receptors to cause unpredictable patterns, and whether we can modify the patterns in logical ways.

Other ongoing interests include investigating the mechanisms that underlie the amazing specificity of odorant gene expression and the molecular biology of neural replacement in the olfactory epithelium. Our foundational studies of gene expression in the cell types of the olfactory epithelium guide these studies and provide opportunities to understand how phenotypic differences arise.

Technologically, our approaches range from genomics to biochemistry, anatomy, and behavior. The mouse is our primary experimental model.
