Chemical engineers are primarily known for their tech-nical expertise. While this engineering know-how has played a key role in developing technologies essential for modern society, it will not be enough to solve the increasingly complex challenges of today’s world. Solutions to these issues, including the development of safe and sustainable food and water supplies, economical alternative energies, and more-effective pharmaceuticals, will require a multidisciplinary approach that considers political, social, and economic constraints, as well as the obvious technical challenges.
