Postdoctoral Research

Victor Faundez's Lab

My postdoc research focuses on a Menkes disease, a progressive form of childhood neurodegeneration that is triggered by dysregulation of copper. Importantly, Menkes disease shares pathogenic mechanisms with both neurodevelopmental and neurodegenerative disorders. I am testing the hypothesis that deficits in ATP7A, a chief transporter required for copper homeostasis, activates the pink-parkin mitophagy pathway in order to trap damaged mitochondria within the soma, thus preventing mitochondria delivery to the synapse in patients with Menkes disease.

Foundation of the Singleton Lab 

Anticipated in 2024

My ultimate research goal is to use systems biology and genetic approaches combined with my training in cellular and molecular neuroscience to investigate the mechanisms that control neuron development in normal and pathological conditions.
