Research Expertise

My research aims to improve our understanding of Parkinson’s disease (PD), a progressive neurodegenerative condition that affects over 1.5 million individuals in the U.S. alone, and for which there is currently no cure. Over the past 10 years, efforts have been focused on three major themes in PD:

1) Role of Protein Misfolding in PD: Histopathological, genetic, and experimental evidence suggest that the aggregation and accumulation of alpha-synuclein (α-Syn), the primary component of Lewy bodies, underlies the symptoms seen in PD. Through the development of novel biophysical, cell-based, and animal models, my work has sought to indentify factors that initiate α-Syn misfolding. Recently, we have demonstrated that aggregated forms of α-Syn are transmissible entities that propagate and spread throughout the brain in a manner akin to prion diseases. This exciting discovery represents a significant shift in our understanding of PD etiology and progression.

2) PD Drug Discovery: Present PD treatments provide temporary relief to motor impairments but do not alter the neurodegenerative process. In collaboration with UPenn’s Center for Neurodegenerative Disease Research Drug Discovery unit headed by Dr. Kurt Brunden, I have been developing high-throughput screening assays to identify small molecules and biologics that inhibit the formation of abnormal α-syn species.

3) Biology of Midbrain Dopamine Neurons: PD is primarily a movement disorder that results from the loss of dopamine-producing neurons in the midbrain. The reasons why this subpopulation is particularly vulnerable in PD is unclear. By characterizing the pathways that govern their development and maintenance, we and others have shown that a susceptible dopamine cells are defined by specific transcription factors that regulate their survival in adulthood.
