Overview of our Research
We apply a multifaceted approach to better understand how the central nervous system forms during development.
Our primary focus is on oligodendrocyte-axon interactions. The image at left shows a single spinal cord oligodendrocyte forming numerous myelin sheaths.
We apply genetics to learn how myelin sheaths are formed & stabilized. The image at left shows accumulation of axonal vesicles (white) at ensheathment sites (yellow arrowheads). We utilize transgenisis and DNA plasmid injection into fertilized eggs in order to genetically manipulate subsets of neurons or glia.
Use of transgenic zebrafish embryos enables us to test hypotheses both in vitro and in vivo.

April 2019. As we wrap up final data analysis and progress reports for the National MS Society funded project, happy to officially announce that we received 5 years of funding from the National Science Foundation (CAREER) to study mechanisms of adaptive myelination. Honored and excited to continue this project. This would never be possible without the hard work and investment by currrent and former lab members, as well as support from the MS Society, WSU Biology Department, College of Science and Engineering, and WSU Foundation.
