Studies of protein folding and aggregation

Proteins generally encounter one of two fates after being synthesized. They can fold to their native structure, which enables them to function normally, or they can misfold to a non-native, non-functional structure, which leaves them vulnerable to degradation or aggregation. Protein folding and aggregation are both critically important processes; the former is integral to life, and the latter is strongly associated with devastating diseases, including Alzheimer's and Parkinson's disease. The goal of our research is to improve our understanding of these processes, with an emphasis on energetics and mechanism.
