The $24 billion Unisuper fund has revamped its internal investment team with the fund promoting four of its staff, hiring an additional three people and adding another person to its investment committee.

"Given Unisuper's rapid growth in funds under management and the quest for superior risk adjusted returns in a complex financial environment, it is imperative that we remain adequately resourced in order to maintain Unisuper's competitive edge in terms of investment expertise," Unisuper chief investment officer David St. John said.

The fund has appointed Graham Dunstan to the fund's investment committee. Dunstan previously worked for the Emergency Services Superannuation Scheme where he was both chief executive and chief investment officer.

Shannon Hansen and Sarah Angliss have each been hired as an investment analyst, investment operations. Hansen's previous job was with QSuper as an investment analyst. Angliss's prior job was with UBS as an associate director.

Brad Green has been appointed to the newly created job of investment analyst, private markets. Green comes to Unisuper from private equity firm Gramercy Venture Advisors.

The fund has also promoted four of its investment staff.

Dennis Sams has been promoted to the head of public markets.  The promotion follows the appointment of Paul Laband to the job as head of strategic titling. Laband's previous job with the fund was as head of public markets.

Unisuper's manager, research and risk management David Schneider will now head this department.

Gautam Rajamani has been promoted to the newly defined job of manager, private markets. Thomas Tam has been promoted as senior investment analyst, private equity.

The fund now has 23 roles within its investment team. Unisuper, however, is looking to fill two of these positions, including manager, public markets and an investment governance and sustainability specialist.
