Each year, Science magazine presents a list of the best employers in the biotechnology and pharmaceutical industries. Employers are ranked on 23 variables, including financial performance, work culture, and academic and intellectual challenge. More than 3,500 scientists around the world are surveyed by the journal, which is published by the American Association for the Advancement of Science.

Among the companies so recognized, DuPont made the list in 2013 for the sixth year in succession. Across six continents, DuPont employs more than 10,000 scientists in the areas of biology, chemistry, materials science, and engineering. Science-driven innovation lies at the heart of the company’s long-term business strategy.

Through the years, their researchers and managers have introduced such ground-breaking technologies as  Teflon® coatings, Kevlar® fibers, Tyvek® house wrap, Nomex® thermal protection, Corian® kitchen surfaces, Plenish® soybean oil, and Sorona® renewably sourced fiber, among dozens of others.

Under the leadership of new Chair and CEO Ellen Cullman, DuPont is continuing its transition from traditional chemicals to a greater emphasis on food science, environmental protection, and renewable energy solutions. Science lies at the heart of the company’s focus. She and the company are encouraging high school and college students in the U.S. to study science, math, and engineering to ensure that companies like hers will be able to continue to conduct R&D activity in the U.S. long into the future.

DuPont believes that by collaborating with customers, governments, NGOs, and thought leaders, it will help find solutions to global challenges related to providing the world with enough food, decreasing dependence on fossil fuels, and protecting life and the environment. That focus means the emphasis on science and innovation at DuPont will be stronger than ever for many years to come.
