Kathryn Graham, one of the most senior investors at the UK’s largest pension fund, has left the organisation after a review tied to the upcoming retirement of its chief investment officer.

Graham, who has a background in hedge funds and alternative assets, joined the £60bn Universities Superannuation Scheme in 2014 as head of strategy coordination. She was in charge of ensuring investment decisions by the scheme’s trustees were implemented as intended, including overseeing external fund managers.
