Research Interests: Our lab focuses on a mechanistic, molecular view of how biopolymers assemble functionally and pathologically. We employ a multi-faceted experimental and computational approach centered around magnetic resonance. Current projects include RNA granule formation and aggregation in neurodegenerative disease; intermediate filament assembly and defects associated with cancers and pediatric disorders; and the structure of the plant cell wall with applications for engineering fossil fuel alternatives and drought tolerance.
