2022 Commencement Speaker, Honorary Degree Recipients

Meet this year's commencement speaker and the individuals being recognized for their outstanding accomplishments and service to the world

Announcing 2022 Commencement Speaker

Duke University will welcome General Motors CEO Mary Barra as commencement speaker and honor four honorary degree recipients at its commencement exercises on Sunday, May 8, in Wallace Wade Stadium, President Vincent Price announced Tuesday. The ceremony begins at 9 a.m. and is open to the public.

This year’s group of honorary degree recipients includes individuals whose career paths took surprising turns, including a medical missionary, a scientist turned entrepreneur, a former NASA engineer who led the Girl Scouts and a Nigerian economist who is working to improve lives across Africa.   

Barra received an honorary degree from Duke in 2018 and is a member of the university’s board of trustees. Barra is the first woman to lead a major auto company. She was elected chair of the GM board of directors in 2016, two years after becoming CEO. 

General Motors’ vision is a world with zero crashes, zero emissions and zero congestion, and as CEO, her focus is on advancing an all-electric future that is inclusive and accessible to all. 

Barra has been ranked atop the lists of the “Most Powerful Women in Business” published by both Forbes and Fortune magazines. She was ninth on Fortune’s list of the “World's 50 Greatest Leaders” in 2020 and was listed as one of the world's 100 most influential people by TIME magazine in 2021. 

Barra began her career with GM in 1980, inspecting hoods and fender panels at the Pontiac Motor Division as a co-op student at the former General Motors Institute (now Kettering University). Before becoming CEO, she led GM’s global product development, purchasing and supply chain, global human resources, and global manufacturing engineering organizations in varying roles.

“Mary Barra models the type of business leadership needed today. She combines an acute intellect with the ability to bring out the best in others through her considerable emotional intelligence and decency,” said Bill Boulding, dean of Duke’s Fuqua School of Business. 

“She genuinely cares about others and takes seriously her responsibility to use business as a positive force for change,” said Boulding. “I’m thrilled Duke’s graduates will get to hear from Mary at such a pivotal time, as they consider how they will make a difference in the world.”

“I am thrilled to welcome Mary Barra and to honor these extraordinary leaders at Commencement in May,” said President Price. “They have made contributions in a diverse range of fields that have transformed countless lives, and I know that they will inspire our graduates to pursue careers of principle and purpose.”
