Quinbrook Infrastructure Partners, an investor concentrating on energy transition, has unveiled several new executive appointments, notably naming Brian Restall as its first-ever Global CEO.

The firm also announced the appointments of Giulia Siccardo as Managing Director and Regional Leader for North America, and Kathryn Lin as Senior Director, spearheading Quinbrook’s digital infrastructure strategies.

The company stated these leadership changes aim to enhance its executive team and bolster ongoing expansion efforts.

Restall, a founding member of Quinbrook since 2015, has been serving as the firm’s Australian Regional Leader, in addition to being part of the Global Investment Committee and Chair of the Global Procurement Committee. In his new capacity, Restall will oversee the management of Quinbrook’s regional teams in North America, Europe, and Australia.

Siccardo joins Quinbrook following her role as the inaugural Director of Manufacturing & Energy Supply Chains at the U.S. Department of Energy in Washington, D.C. Lin became part of Quinbrook in 2023 and has been functioning as a Director within the North American investment team.

David Scaysbrook, Co-founder and Managing Partner of Quinbrook, remarked, “As Quinbrook grows, we have been working to establish a leadership structure that further empowers our people to lead our firm into its second decade and beyond. As Co-Founders, Rory and I are proud of what we’ve built together since establishing the firm in 2015. We believe this new leadership structure equips Quinbrook with exceptionally talented leaders as we continue our journey as a value-add specialist in the energy transition.”
