At Chemours, scientific excellence extends beyond discovery. It includes the ability to transform ideas into scalable technologies, preserve critical knowledge, and empower others to build on that foundation. To recognize individuals who consistently demonstrate these principles in action, Chemours has named four distinguished researchers as recipients of its inaugural 2026 Catalyst for Scientific Excellence Award.
The company’s highest scientific honor, the Catalyst for Scientific Excellence Award, recognizes careers defined by innovation with impact and commitment to developing others. The Award highlights individuals whose work strengthens not only Chemours’ innovation pipeline, but also the systems of knowledge-sharing and safety that enable scientific progress to scale across teams and geographies. This year’s honorees include Greg Chapman, Jodi Witt, Karl Krause, and Xuehui Sun.
“Thank you for the innovation you deliver, the knowledge you preserve, and the people you help develop along the way,” shared Chemours President and CEO Denise Dignam in recognition of the awardees.
