Biography
I am interested in determining the structure and dynamics of partially disordered and complex macromolecular systems, in particular protein aggregates and semicrystalline polymers. My primary experimental tool has been solid-state NMR. Much of my work relies on spin dynamics based computation and database-driven analysis to develop SSNMR methods and understand results.
