Research Interests
-NMR spectroscopy
-Protein structure and dynamics
-Biomolecular solid-state NMR
-HIV structure and assembly
-Nanoparticles and bionanomaterials
-Protein-drug interactions


Our group studies biomolecular assemblies and interactions using solution and solid-state NMR spectroscopy. We are interested in HIV proteins and their structural mechanisms in virion formation, maturation, and their inhibition. In addition, we implement state-of-the-art spectroscopic methods to understand protein-protein and protein-drug interactions related to human disease and therapeutic strategies.

We also develop NMR-based techniques to characterize polymer assemblies designed for carbon capture and to elucidate biomineralization mechanisms. This biomimetic nanomaterials project is a DOE-funded collaboration with Pacific Northwest National Laboratory (
