Our lab has two major areas of study: we examine (1) the neurophysiological, morphological, and behavioral development of the taste system, and (2) injury induced degeneration and regeneration in the peripheral and central gustatory system. Specific projects focus on environmental and physiological factors affecting the developing and regenerating taste system, anatomical and functional development and plasticity of the gustatory brainstem, and the role of neurotrophins in maintaining peripheral and central taste structure and function.
