Dr. Heavner received her Ph.D. in Genetics and Molecular Biology from the University of North Carolina, where she worked in the lab of Dr. Larysa Pevny investigating transcriptional regulation of retinal development using mouse genetics as a primary tool. Enamored with gene regulation and neural development, Dr. Heavner then joined the labs of Dr. Susan McConnell and Dr. Gill Bejerano at Stanford University to study cortical development from a genome-wide perspective.  While at Stanford, Dr. Heavner received one of the inaugural Stanford Neurosciences Institute Interdisciplinary Scholar Awards, which allowed her to explore neuroscience, writing, and teaching more broadly. Increasingly interested in synaptic plasticity, Dr. Heavner then traveled up to Seattle Children's Research Institute to work in the lab of Dr. Stephen E. P. Smith, where she studied the roles of synaptic scaffolding proteins in neural activity and Autism Spectrum Disorders. Dr. Heavner has come full circle, back to her neural progenitor roots, to help lead the lab of Dr. John Ngai (Molecular Neurobiology Section), investigating signaling pathways important for neural regeneration during homeostasis and after injury.

The long-term goal of our lab is to identify the molecular pathways regulating the construction or repair of neural circuits.  Our primary model is the the mouse peripheral olfactory system, which is useful for studying adult stem cell-mediated regeneration, because it retains the ability to generate new neurons throughout the lifespan of the animal. We use a combination of approaches, including single-cell transcriptomic and epigenomic analyses, mouse genetics, viral transduction, immunohistochemistry, multiplexed RNA in situ hybridization, primary tissue culture, and confocal microscopy, to predict and test determinants of neural regeneration from a variety of angles.
