He replaces Dan Houlihan, who was promoted to head of asset servicing, Americas last year.
Mr. Burns will be responsible for overseeing client service and setting the direction for the firm's strategy for its investment manager clients in the Americas region. He will report to Mr. Houlihan.
Mr. Burns was head of GFS client service in North America. No replacement has yet been named so he will continue in the client service role as well, Mr. O'Connell said.
Northern Trust had $1.1 trillion in assets under management as of Dec. 31.
