Mercer, a subsidiary of Marsh, has named Niall O’Sullivan as global chief investment officer.
As Global CIO, O’Sullivan will be expected to lead the full range of Mercer’s investment capabilities, from research to investment solutions and performance, across traditional and alternative asset classes.
O’Sullivan joins from Neuberger Berman, where he had been CIO for multi-asset strategies within EMEA since 2022. Before this, he had been CIO for Mercer Global Investments Europe for 12 years.
Going forward, all asset class teams will report to O’Sullivan, who will be based in London for the role.
O’Sullivan succeeds Hooman Kaveh, who will assume the newly created role of executive chair for Mercer’s Investment Platform. O’Sullivan and Kaveh will report to Michael Dempsey, Mercer’s president for investments and retirement, and remain based in Dublin.
“Niall’s deep knowledge of our investment business, passion for achieving strong investment outcomes for our clients, and ability to foster high-performing teams will position us strongly for the future,” says Dempsey.
“Continuing to work together, both Niall and Hooman will help accelerate the integration of our expanding investment capabilities, scale our differentiated offerings, and deliver consistent, impactful outcomes for our clients,” he continues.
In his new capacity, Kaveh will lead a number of key strategic initiatives, including a focus on M&A, integrating AI into Mercer’s investment processes, and providing custom training and development resources to help colleagues optimize Mercer’s expanding range of investment capabilities. He will continue to chair the Investment Governance Committee.
