Ruda had been the deputy director of business development and strategy. He joined the port authority in 2017 after a 25-year career in transportation that included 12 years in senior management at the Port of Portland.
He replaced Molly Campbell, who earlier announced she was leaving the port authority to accept a 2019 fellowship with Harvard’s Advanced Leadership Initiative.
The port authority said it had initiated a national search for a permanent director. Meanwhile, Ruda will work closely with the newly named team of general managers and deputy general managers at the New York and New Jersey marine terminals.
Robertson previously served as the vice president of business and e-business for Jacksonville, Fla.-based CSX Transportation. He also held management roles at ProLogis and Cherokee Investments.
In his new role, Robertson will oversee the port’s engineering services, environmental planning and compliance, operations, and safety and security functions and personnel.
