Simmons & Simmons has appointed equity derivatives specialist Sau-Wing Mak from Wachovia Bank's legal team.
Mak, who will join the firm's China financial markets group, was previously senior legal counsel of Wachovia Bank.
Although based in Hong Kong, Mak will serve Simmons' clients across Asia and is set to develop the firm's equity derivatives practice.
Mak will be aided in developing the practice by capital markets managing associate Kevin Tong, who she has worked with previously at Linklaters.
"[The] appointments are part of the strategic growth of our international financial markets group," said the group's head, Jeremy Hoyland.
