Research Interests

Friedreich's ataxia (FRDA) is the most prevalent form of recessive cerebellar ataxia and it is caused by mutations in Frataxin (FXN). Frataxin (FXN) is required for normal mitochondrial function and intracellular iron homeostasis. We have recently shown a mitochondria independent pathway through iron accumulation, sphingolipid synthesis and ectopic activation of the PDK1/Mef2 signaling leading to neurodegeneration in both Drosophila and mouse models. Currently I am investigating therapeutic potential of manipulating the sphingolipid/PDK1 pathway to suppress the neurodegenerative features caused by loss of FXN.
