A bioinformatician turned serial entrepreneur, Driscoll began his career as a software engineer on the Human Genome Project, holds a PhD in Bioinformatics from Boston University and an AB from Harvard, and has spent three decades arguing that metrics, not tables or dashboards, are the real interface between data teams and the businesses they serve.
