Roberto Zoncu, Ph.D.
SAB Member

Roberto is a professor of Molecular Therapeutics in the Department of Molecular and Cell Biology at the University of California, Berkeley. Prior to UC Berkeley, Roberto was a postdoctoral fellow at MIT’s Whitehead Institute, where he worked in Dr. David Sabatini’s laboratory. Roberto combined biochemical and microscopy-based assays to understand how lysosomes govern the signaling activity of the master growth regulator, mTORC1 kinase, and how these organelles generally function as metabolic signaling centers. For his doctoral studies, Roberto joined Dr. Pietro De Camilli’s laboratory. He used advanced microscopy and chemical genetic techniques to interrogate how a class of phospholipids known as phosphoinositides control endocytic vesicle traffic and maturation.

Roberto holds a Ph.D. in Cell Biology at Yale University. He studied molecular biology at the University of Pisa in Italy.
