Chicago-based commercial real estate service firm Jones Lang LaSalle has hired a new CEO. Colin Dyer, 51, who is now CEO of WorldWide Retail Exchange, will become the next CEO of the 17,000-employee firm on Sept. 7. Jones Lang LaSalle manages roughly 725 million sq. ft. of commercial real estate space globally.

WorldWide Retail Exchange is a global consortium of retailers that leverages Internet technology to garner efficiencies from the supply chain. The appointment of Dyer comes six months after Jones Lang LaSalle CEO Chris Peacock resigned from the firm, citing personal reasons for his departure.

The announcement marks the second major CEO change within the commercial real estate brokerage industry this summer. Last month, Cushman & Wakefield announced that North American division president Bruce Mosler would become CEO of the firm starting in 2005.
