General Information

The lab uses biophysical, genetic, structural, and design strategies to study the relationship between the sequence, stability, and three-dimensional structures of proteins.

We are also interested in the mechanisms that intracellular proteases use to select the correct targets and how ATP-dependent proteases catalyze protein denaturation.
