Man Group’s hedge fund unit has hired Samantha Rosenstock to lead its relative value and private markets strategies.

Rosenstock will be based in New York, reporting to Jens Foehrenbach, the chief investment officer of Man FRM, according to a statement Tuesday from the firm. She was previously head of alternative investment form the State of New Jersey’s $77 billion pension fund.

At New Jersey’s division of investment, Rosenstock helped manage the public pension’s portfolio of hedge funds, private equity, private credit, and real estate. She’s returning to the private sector to help build out the private markets products at Man FRM, a fund-of-funds unit with $17.5 billion of assets under management at the end of March.

“I look forward to helping Man FRM further develop its private markets capability to meet the growing institutional investor demand for customized portfolios which can incorporate both liquid and illiquid alternative investment strategies,” Rosenstock said in the statement.

Man Group, a London-based investment manager with about $113 billion of assets at the end of March, bought FRM Holdings in 2012. The division provides its predominantly institutional clients with hedge fund services such as management accounts and co-mingled strategies, according to its website.

Before joining New Jersey’s pension fund, Rosenstock was a director in Société Générale’s advisory group for alternative investments and held senior hedge fund research roles at PineBridge Investments — the former asset management arm of insurance giant American International Group — and Ivy Asset Management.

Rosenstock graduated from Wesleyan University with a Bachelor’s degree in mathematics in 1998, and started her finance career the following year as a quantitative model developer and trader at R.G. Niederhoffer Capital Management, according to her LinkedIn profile.
