His research specialty is single-cell proteomic investigations of developing human systems. Sean’s PhD work involved dissecting protein regulators of human pluripotency using embryonic stem cells and mass spectrometry-based proteomics. He then went onto Stanford University where he trained under Professor Garry Nolan, pioneering CyTOF mass cytometry - a next-generation single-cell analysis platform. Sean’s work in mass cytometry analysis has gone on to provide an unparalleled granularity of understanding in multiple facets of hematopoiesis and immunology. His work has been recognized by numerous awards including the Damon Runyon Cancer Research Foundation “Breakthrough Scientist” award and the International Society for the Advancement of Cytometry President’s Award of Excellence.
