Ronald J. Unnerstall
Group Head, Engineering; and Vice President, Refining and Logistics Technology, BP
The son of an engineer, Ron Unnerstall first applied the core engineering concepts he learned at Purdue during an internship at an Amoco refinery, located in his mother’s hometown of Whiting, Indiana. After graduating with a degree in chemical engineering, he began his career at Amoco — where he advanced into leadership positions.
In 1998, when BP acquired Amoco as part of a multibillion-dollar megamerger, Unnerstall and his family relocated to London, BP’s corporate headquarters. The merger capitalized on Amoco’s strength as an energy operator and BP’s expertise in financial and strategic planning.
Unnerstall attributes his success to a commitment to safety, rigor in operations and a focus on building long-term value. He believes that in our increasingly global environment, solving difficult engineering problems requires global collaborations.
Unnerstall’s work still takes him around the world, but he now resides in the Chicago suburbs.
