studies structure and function of proteins involved in the autophagic pathway.

Powers, Evan  
is interested in the energetics and mechanisms of protein folding and aggregation.

Schmid, Sandra  
is defining the molecular mechanisms of receptor-mediated endocytosis, which involves the concentration of receptor-ligand complexes into clathrin coated pits, their internalization via coated vesicles, and the regulation of these events by GTPases and kinases.
