Company Group Chairman, Johnson & Johnson, 53
New MPW Taubert expanded her role last year at the health care giant’s pharmaceuticals business when she added Latin America to her list of responsibilities. As head of the Americas for Janssen, she oversees more than $20 billion—nearly 30% of Johnson & Johnson’s total revenues. That figure has doubled since she took on the role in 2012. The industry veteran has been pushing big data and analytics to help J&J solve some of medicine’s most pervasive challenges, including cardiovascular and metabolic diseases and serious mental illness.
