My research focuses on the design principles of molecular circuits that govern cell decision-making and responses. My lab has made contributions in understanding the molecular machinery of cell signaling and how molecular modules have been used in evolution to build novel new behaviors. Most recently, I have been a pioneer in the emerging field of synthetic biology, exploring how these design principles can be harnessed to engineer cells with customized therapeutic response programs. I am an author of the textbook, Cell Signaling (Garland Science 2014) and was the founder of the cell therapy biotech startup, Cell Design Labs, which was acquired by Gilead Biosciences in 2017.
