Research Summary

We study how biomolecules in a cell self-organize. In particular, we are interested in understanding how membrane-free cellular compartments such as RNA granules form and function. Our lab develops new biochemical and biophysical techniques to investigate these compartments and to understand their dysfunction in human disease.
