Browne produces independent research reports and works directly with companies of all sizes. One of his niches is consulting on new diagnostic tools—for example, in his work with RAIsonance, a startup using machine learning to analyze cough sounds correlated with tuberculosis and covid-19. For multinational corporations, he models threats such as the possibility of avian influenza spreading from human to human. He builds most- and least-likely scenarios for how the global business community might react to an H5N1 outbreak in China or the US. “I never want to be right,” he says of worst-case predictions.
