Areas of Interest

My research group focuses on the investigation of the dynamic structures and function of membrane-associated proteins and protein-protein complexes, and understanding the role of membrane composition on protein folding, misfolding, and aging-related diseases. Two of the major research areas are: (1) Understanding folding/misfolding, aggregation, and toxicity of amyloid proteins (such as islet amyloid polypeptide (IAPP or amylin), amyloid-beta, alpha-synuclein) and the molecular processes governing liquid-liquid phase separation (LLPS). The many roles of cofactors (such as lipid membrane, metals, metabolites and small molecules) influencing protein aggregation are also investigated. (2) Development and applications of nanodiscs to study the structure and function of cytochrome enzymes and GPCRs. A variety of cutting-edge biophysical and biochemical approaches are used to address the biomedically important questions related to these topics.
