About THORBURN JAMES M

James M. Thorburn is a senior finance and operations executive best known for serving as Chief Financial Officer of Twist Bioscience Corp., a U.S.-listed synthetic biology company focused on DNA synthesis and related life-science applications. He joined Twist as CFO in April 2018 and later stepped away from the CFO role when the company appointed Adam Laponis, effective January 8, 2024.

He served on the Board of Directors of IXYS Corporation, a publicly traded semiconductor company, from March 2007 through January 2018. He was also Chief Sales Officer and Co-Head of International at Televerde from August 2014 to February 2018, bringing together commercial leadership and international oversight. Earlier in his career, he held interim CFO roles at several public and private companies, including Enercore, Next Autoworks, Fisker Automotive, and Numonyx. He also served as Chief Executive Officer of Zilog from March 2001 to August 2006. Prior to that, he held multiple executive positions, including Chief Operating Officer at ON Semiconductor, operating consultant with Texas Pacific Group, Chief Financial Officer at Zilog, and various management roles at National Semiconductor Corporation.

At Twist Bioscience, he supported a period of scale-up and strategic execution as the company expanded its industrial platform and financial capabilities. His earlier CEO experience at Zilog, together with senior finance and commercial roles at Televerde and IXYS, suggests a leader comfortable operating at the intersection of strategy, investor expectations, and execution. Because public sources do not provide enough detail on specific standalone decisions he led, the most accurate profile is a conservative one: a seasoned executive with a long record in finance, operations, and governance, particularly in technology-driven organizations.
