He earned a series of rapid promotions and served in a number of engineering, financial, manufacturing and leadership management roles in Europe and Asia, and at the company’s headquarters in the United States.

Gilson has focused his career on specialty chemicals and performance materials since 1999, when he was a director of science and technology for Dow Corning’s Specialty Chemicals unit. Under his leadership, the company patented several key new products. In 2003, he was named vice president and general manager for the Advanced Technologies and Venture Business, where he was responsible for a portfolio of activities that included products for the solar, electronics, opto-electronics and semiconductor industries. Gilson relocated to Japan in 2005 as vice president and general manager and Asian area president to oversee the company’s multi-billion dollar global Specialty Chemicals business. He was later named executive vice president of Dow Corning in 2009.
