Brief Description of Research Interest :

My research focused on molecular chaperones that degrade and remodel client proteins. Molecular chaperones play central roles in development and cell cycle. The decline in the function of molecular chaperones correlates with many pathological conditions, including neurodegenerative diseases. I am especially interested in how different molecular chaperones recognize and engage their respective targets and use the energy of ATP hydrolysis to guide protein folding or unfolding. I am exploiting a variety of structural biology, microscopy, and biochemical methods to address these questions.
