Lori J. Ryerker

ISU B.S. Chemical Engineering 1983

Retired Chairman, CEO and President of Celanese

Lori Ryerkerk is a visionary leader in the energy and chemical industries and a dedicated advocate for women in engineering. With more than four decades of experience at Celanese Corporation, Shell, Hess Corporation, and ExxonMobil, Lori has built a reputation for transformative leadership and strategic innovation.

Lori currently serves on the Board of Directors for Eaton Corporation, Norfolk Southern Railway and Cencora. From 2019 through 2024, she served as CEO and Chair of Celanese Corporation, a Fortune 500 global chemical and specialty materials company. Under her leadership, Celanese experienced remarkable growth, achieving $11 billion in sales, and earning recognition for its sustainability initiatives, corporate citizenship, and inclusion efforts.

Lori’s journey from an Iowa State chemical engineering graduate to one of the 47 female Fortune 500 CEOs is a testament to her dedication and innovative spirit. But her impact extends beyond the boardroom — she is a passionate mentor and advocate for the Women in Science and Engineering (WiSE) program at Iowa State. She co-founded the Ryerkerk-Griffith WiSE Faculty Fellowship, which strengthens educational offerings and enhances the program’s prominence on campus. In addition, the Ryerkerk-Griffith Completion Grant in Engineering provides financial assistance to undergraduate students facing financial hardships, helping them complete their degrees.

Lori and her husband, the Honorable Carl R. Griffith, are longtime supporters of Lamar University and the Lamar University Foundation. Both were actively involved as volunteers and donors for many years prior to their marriage in 2017. In recognition of their sustained generosity, they were named members of the Mirabeau Society in 2020 and the Lamar University Legacy Society in 2021.

Lori has served on the Lamar University College of Engineering Advisory Council since 2004 and joined the Lamar University Foundation Board of Trustees in 2018. She served as an Executive in Residence Speaker in 2006.

Through a generous $1 million planned gift, Lori and Carl established the Carl R. Griffith and Lori Ryerkerk Griffith Scholarship in Criminal Justice and the Carl R. Griffith and Lori Ryerkerk Griffith Scholarship in Engineering, further strengthening educational opportunities for future Lamar University students.

Lori’s leadership and contributions to the chemical industry have been widely recognized. Her exceptional leadership was honored in 2020 when she was named D Magazine’s CEO of the Year. In 2022, she received the prestigious Kavaler Award from The Chemists’ Club, an honor voted on by her peers to recognize outstanding leadership and innovation in the global chemical sector. In 2025, she was honored as the Recipient of the Petrochemical Heritage Award, by the Science History Institute, the Founders Club and the American Fuel and Petrochemical Manufacturers. She has also been inducted into the Iowa State University Chemical and Biological Engineering Hall of Fame and received the Iowa State Alumna Award in 2025.

As part of the Subaru Loves the Earth® initiative, JK Subaru is partnering with the Arbor Day Foundation to give our community trees that are ready to be planted, free of charge. Planting a tree helps cool neighborhoods, improve air and water, and create habitat for wildlife. A variety of regionally appropriate trees will be available for you to choose from to enhance the beauty of our surroundings while making an impact on the environment. We are partnering with them to help distribute these trees, and we would love if you would reserve a tree to have them planted locally!
