Research Interests

Our lab goal is to understand glial function at the animal, cell, and molecular level in order to elucidate mechanisms of normal development and disease progression.

The main research focus includes:

  • The role of Golgi outposts in acentrosomal microtubule nucleation in oligodendrocytes.  Our lab is investigating partner proteins that work in concert with the microtubule nucleator TPPP to organize microtubules. In addition, we are making important observations on the biophysical properties of TPPP and how this can lead to aggregation in neurodegenerative diseases.
  • Mechanisms of mRNA transport in oligodendrocytes. Our lab is using mouse models to understand the importance of mRNA transport in in vivo myelination. We are also using biochemical and biophysical techniques to identify the molecular players involved in these transport processes.

Current Projects

New topics of interest include:

1. Mechanisms of leukodystrophies. This is a disease primarily affecting children and results in inefficient myelination. Because many leukodystrophies are caused by an underlying genetic mutation, we believe these mutated genes also help inform us of critical and understudied steps in normal myelination.

2. Cytoskeletal organization of astrocytes. Astrocytes are ramified cells that contain microtubules, actin, and intermediate filaments, but it is unclear how these 3 classes of cytoskeleton interact with each other to form the complex morphology of astrocytes.
