ABOUT ME & MY RESEARCH
I am interested in neural plasticity, specifically how the adult brain changes its structure in response to altered sensory input. My model system is the zebrafish olfactory system. For over 20 years I have been exploring the potential of the adult zebrafish olfactory bulb to recover from injury and disease.
I am also fascinated by developmental processes, and I am fortunate enough to work in a part of the nervous system that is continually developing. The olfactory system is amazing in that the peripheral organ exhibits neuronal turnover and the olfactory bulb is one of the very few places in the adult brain that has persistent neurogenesis. How cool is that?
