Tess Branon, along with her graduate advisor Professor Alice Ting (Stanford, MIT), co-developed transformative proximity labeling-mass spectrometry technologies such as TurboID to map protein-protein interaction networks in living systems. She has since supported researchers worldwide in applying these methods to a wide range of biological questions across diverse model systems. Now at Genentech, Tess continues to advance interactomic technologies to drive drug discovery and therapeutic research.
