Point72 Asset Management has named Michael Fisher as its new Chief Risk Officer, adding to a series of recent executive shifts as Steve Cohen steps back and Harry Schwefel takes the reins at the hedge fund, according to a report by eFinancial Careers.

Fisher joined the New York-based firm from Citadel, where he was Head of Risk for Global Fixed Income and Macro for the past three years.

Fisher, a former "strat" at Goldman Sachs, brings extensive experience to Point72. He originally joined Goldman in 2003 as a PhD mathematician and spent 17 years there, rising to Managing Director in 2011. Fisher takes over from Mike Jemiolo, who served as Point72's CRO for a decade before departing in June.
