Mr Flood will be responsible for the continued development of AXA IM in the Asia Pacific region.
He first joined AXA IM from Lion Global Investors where he was chief investment officer, and has held a number of senior investment roles across the asset management industry.
AXA IM's global head of client group, Laurent Seyer, said Mr Flood will bring invaluable investment management experience along with extensive knowledge of the challenges and opportunities offered by the region.
“Our focus as a business is on growing third party assets through geographical expansion, client segmentation and further strengthening of our product offering,” said Mr Seyer.
“Asia is a key market for us, and with Simon on board we will work to accelerate our expansion in Asia, building on the solid foundations achieved by Jean-Pierre Leoni and the team over the past few years.”
