The Kalocsay Laboratory is using quantitative mass spectrometry to understand receptor signaling. We have pioneered proximity sensitive proteomics to precisely define functional interactions in situ at unprecedented temporal and spatial resolution and developed proximity phospho-proteomics to precisely follow protein phosphorylation during signaling. We plan to harness these breakthrough technologies to define receptor signaling using experimental models for tumor immune evasion in the future, with the goal of understanding disease mechanisms and developing new therapeutics.
