Gabrielle is a seasoned expert in talent strategy and management, with deep experience in C-level human resources leadership. Currently the Chief Operating Officer at Keystone Strategy, a global technology and advisory firm, she oversees finance, human resources, IT, marketing, and facilities. Gabrielle has been instrumental in the growth of some of the world's most innovative companies, including her pivotal role in shaping Tesla's human resources and organizational strategy under Elon Musk during the company's most disruptive years, and serving as an Executive in Residence for Comcast Ventures.

"Gabrielle's appointment to IonQ's Board of Directors strengthens our leadership at a time of rapid growth and transformation for the quantum industry," said Peter Chapman, Executive Chair of IonQ. "Her experience guiding some of the world's most innovative companies, combined with her deep expertise in talent strategy and executive leadership, will be integral to our team as IonQ continues to scale and expand our impact in the quantum computing and networking industries."

Gabrielle has served on a number of public and private boards with a focus on executive leadership and compensation strategy. She currently serves on the boards of Fountain, a private technology company focused on frontline workforce management, and Altanine, a private pharmaceutical company.

"IonQ is at the forefront of the quantum computing revolution, and I am excited to join the board during such a pivotal time," said Toledano. "The company has made incredible strides in bringing quantum computing and networking to enterprise and government applications, and I look forward to further contributing to IonQ's strong growth trajectory."

Also announced today is the departure of Harry You from IonQ's Board, effective immediately. Harry decided to step down from the Board to lead a private AI-healthcare company.

Added Peter Chapman. "On behalf of the Board, we thank Harry for his tremendous dedication and contributions since we began our journey as a public company and wish him all the best in his future endeavors."

Today's announcements follow last year's IonQ board appointments of Robert Cardillo (Chairman and Chief Strategist of Planet Federal) and Bill Scannell (Dell Technologies' President of Global Sales and Customer Operations).

These strategic board appointments also complement recent milestones in IonQ's growth.
