For one story, “The hunt for dangerous doses,” investigative reporter Sam Roe led a collaboration with data scientists, pharmacologists and cellular researchers at Columbia University Medical Center in an attempt to discover potentially deadly combinations of prescription drugs. Intrigued by the novel data mining algorithms developed by Columbia scientist Nicholas Tatonetti, Roe proposed that the two team up to search for drug combinations that might cause a potentially fatal heart condition. Roe also recruited Dr. Ray Woosley, the leading authority on that condition and a former dean of the University of Arizona medical school, to the team. Over two years, as he orchestrated the project, Roe traveled to New York 12 times to meet with Tatonetti. They brainstormed, analyzed data and talked with Woosley via conference calls. Several of Tatonetti's graduate students joined the team, as did Columbia cellular researchers whose work provided a critical layer of validation of the results.
