Computer Sciences Corp. named Mike Lawrie president and CEO, assigning him two of the three top positions held by retiring president, CEO and board chairman Michael Laphan, according to a CSC news release.

Current CSC board member Rodney Chase has been appointed nonexecutive board chairman of the Falls Church, Va.,-based military, national security and health information technology company, according to the release. Chase's appointment will take effect when Lawrie assumes the president and CEO roles—expected to occur no later than March 31, according to the company.

Lawrie, 58, who also was named to the CSC board, joins CSC from UK-based IT company Misys, where he served as CEO. Lawrie served as a leader for Misys in a series of transactions with Allscripts Healthcare Solutions. Those began in 2008 with the formation of Allscripts-Misys Healthcare Solutions, in which a Misys unit held a controlling interest; in 2010, Allscripts extricated itself from majority control by Misys in a $1.3 billion deal to acquire health IT systems developer Eclipsys. Lawrie previously worked for 27 years in various executive positions at IBM Corp.

The announcement of Lawrie's appointment as president and CEO comes less than two months after the company reported a major loss on its $1.5 billion investment in an electronic health-record system contract with the U.K.'s National Health Service.
