Brunel is currently chief executive of Gecina, a Paris-based retail estate investment trust that owns almost €20bn (£17.2bn) in office and residential assets.
Her career in retail estate began in construction, where she delivered major residential and office development sites. In 2003, she joined Gecina as executive director of strategic development, before her appointment as chief executive of Eurosic in 2006.
Brunel rejoined Gecina in 2014, where she was later appointed as chief executive in 2017. Alongside her career in retail estate, Brunel is a civil engineer, holds an MBA from the HEC Paris School of Management, and is a fellow of RICS.
David Tyler, chair of the board at Hammerson, said: “Méka has exceptional experience in the European real estate sector, and we look forward very much to welcoming her to our Board.
“With close to half of our property portfolio outside of the UK, we are pleased to strengthen our European expertise. In addition, as we build momentum with our City Quarters concept, we will benefit from her experience and skills in property outside of retail.”
