My research interest is regarding protein folding and misfolding behaviors in order to answer how proteins can fold into its native structure and how certain proteins can misfold and cause disease. Studies about protein folding are mainly the development of new methodologies to explore the folding process in order to unravel the intrinsic folding properties. Studies about protein misfolding are focus on two diseases: prion disease and Alzheimer’s disease. We are interested in studying the mechanism of amyloid fibril formation, factors influencing molecular assembly, designing inhibitor for amyloid formation, and species barrier in prion disease.
