Dr. Guerriero's PhD research focused on the role of lipid metabolism in
biosynthetic protein trafficking in polarized epithelial cells. This research
spawned his interest in the folding and trafficking decisions that occur early in the biosynthetic pathway. In 2009, he joined Dr. Jeff Brodsky's lab to study the mechanisms that select and target misfolded proteins for degradation in the secretory pathway, termed ER-associated Degradation (ERAD). 


Currently, Dr. Guerriero's research is focused on understanding the
quality control machinery that recognizes misfolded membrane-spanning proteins. His research has recently expanded to include computational modeling of ERAD substrate hydrophobicity and how it impacts the degradation process.
