He joined Lubrizol in 1981, rising to the director of investor relation's position. That role ended with Lubrizol's 2011 acquisition by Warren Buffett's Berkshire Hathaway.

Until August, Sutherland worked as VP-IR for WR Grace & Co.

At the Lubrizol Foundation, Sutherland takes over for Dave Enzerra, who has shifted to a corporate operations role.

Lubrizol employs 7,500 people and generated $6.4B in revenues during the past year.
