Jennifer Petriglieri, associate professor at INSEAD, studied more than 100 couples where both partners have big professional goals. She finds that being successful in your careers and your relationship involves planning, mapping, and ongoing communication. She also identifies different models for managing dual-career relationships and explains the traps that couples typically encounter. Petriglieri is the author of the book “Couples That Work: How Dual-Career Couples Can Thrive in Love and Work.”
