Jeehye Park

Dr. Jeehye Park received her PhD from Jongkyeong Chung lab at Korea Advanced Institute of Science and Technology (Daejeon, South Korea), where she studied the molecular mechanism of Parkinson’s disease. She completed postdoctoral training in Huda Zoghbi lab at Baylor College of Medicine (Houston, USA) and studied spinocerebellar ataxia type 1.

Research

Dr. Park’s lab's current focus is investigating the molecular pathogenesis of a neurodegenerative disease called amyotrophic lateral sclerosis (ALS) and identify therapeutic targets to develop treatments for ALS patients. Mutations within RNA binding protein (RBP)-encoding genes have been implicated in ALS, but how mutations in RBPs lead to motor neuron degeneration is not clear.

Her lab studies one of the under-characterized RBPs called Matrin3 (MATR3) involved in RNA splicing and is investigating how ALS-linked mutations alter the function of MATR3 and cause motor neuron degeneration. The research team is is using an interdisciplinary approach by combining biochemistry, molecular and cellular biology, fruit fly and mouse genetics, high-throughput forward genetic screens and whole transcriptome analysis.
