Water and renewable energy specialist firm Mattila Lawyers has appointed former Minter Ellison lawyer Karen Lang as a senior associate to lead its infrastructure team.

Lang's expertise in infrastructure and construction law combines a broad range of experience in front-end construction projects with a strong focus on government-funded infrastructure.

"Karen is going to make a great contribution to the firm and to the critical energy and resources sectors we work in," said managing partner Jenni Mattila. "She will be a key addition to the team working on the Commonwealth Government's private irrigation infrastructure operator's program as well as other water infrastructure projects around Australia."
