About

I am Chief Financial Officer of Aperam and I work closely with the Leadership Team, investors, and partners to support Aperam’s financial performance, strategic execution, and long-term value creation, with a strong focus on disciplined capital allocation and leadership in the circular economy. Since joining the Group in 2003, I have held multiple leadership roles across strategy, operations, and marketing in Europe, South America, and the United States. Most recently, I served as CEO of Services & Solutions and Chief Marketing Officer for Stainless Europe, where, together with exceptional teams, we expanded market share across Aperam’s global service network, launched the largest stainless steel e-commerce platform outside China leveraging automation and AI, and partnered with R&D and customers to deliver sustainable, future-ready steel solutions. I am driven by collaboration, customer focus, and continuous transformation, and I value building high-performing teams that deliver impact in complex, global environments.
