Muysken rejoins the firm from the hedge fund industry, having recently been portfolio manager for Thames River Capital’s multi-manager alternatives team. Prior to this he worked at Mercer for 14 years, in which time he became global head of research.

In his new role at Mercer, which he takes up this month, Muysken is responsible for overseeing investment strategies that involve exposure to “alternative alpha” – defined by the firm as “underlying investment strategies that make significant use of short selling, leverage or derivatives, or which are narrowly niche-focused or esoteric in nature”.  He is also charged with developing new products and will work with the 25-strong investment management research team in the alternative space.

Muysken will be based in London and report to Rich Nuzum, president and global business leader for Mercer Investment Management.
