Research Summary

We study protein folding and intracellular trafficking in the yeast S. cerevisiae. Our work focuses on the protein folding in the endoplasmic reticulum (ER), quality control mechanisms in the ER, and membrane protein sorting in Golgi compartments. We combine genetic, biochemical and cell biological methods to gain an understanding of the molecular mechanisms underlying each of these processes.
