Overview

My research aims to understand how changes in the dynamics and distribution of mitochondria contribute to synaptic dysfunction and axonal neurodegeneration in neurodegenerative diseases. We are currently investigating the involvement of mitochondrial dynamics in Friedreich’s Ataxia, using cultured neurons and in vivo mouse models. We are also generating novel transgenic mouse models where normal mitochondrial distribution in neurons is altered.

For the past few years, our research has focused on studying abnormalities in axonal dynamics of mitochondria (transport, fusion, and fission), an emerging topic in the field of neurodegenerative diseases. We have dedicated efforts toward developing novel microscopy-based, live imaging assays to assess the role of mitochondrial dynamics to disease pathogenesis both in vitro and in vivo. In the future, we plan to combine these live imaging assays with molecular approaches to identify the mechanisms that cause axonal transport abnormalities in certain neurodegenerative diseases and to investigate the spatial and temporal relationship between mitochondria and synaptic plasticity.
