Rebecca Van Dyck

Van Dyck, a 1991 graduate and soccer player who still plays competitively, has a big task since joining Facebook in February. To be sure, it's a lot higher-profile than her last job, as chief marketing officer of jeans maker Levi Strauss & Co. Van Dyck worked at Apple for several years, where she was senior director of worldwide marketing communications and advertising. Before that, she was the global account director for Nike at Wieden+Kennedy advertising for 12 years. At Macalester, she majored in history and psychology and studied abroad at the University of Cairo.
