Germany's largest bank has bolstered its technology capabilities with an executive appointment.

Deutsche Bank has appointed René Keller as chief information officer of its private, wealth and commercial clients division.

Keller is currently group CIO at Deutsche Börse, a marketplace operator for securities trading, where he is responsible for information technology solutions and service delivery. He will assume his new role in June, succeeding Wolfgang Gaertner who retired at the end of November last year. Based in Eschborn, Germany, Keller will report to Deutsche Bank's group chief operating officer Kim Hammonds. 

He was previously COO of financial software company Information Mosaic and has also held technology roles at Swiss Life, Credit Suisse and UBS.

“René’s track record of successfully delivering technology transformation initiatives in financial services will prove invaluable to Deutsche Bank,” said Hammonds.

The appointment follows that of Pascal Boillat who was named Deutsche Bank's CIO and head of operations, corporate and investment banking in December.

The Frankfurt-listed bank recently reported a net loss of €2.1 billion ($2.28 billion) for the fourth quarter of 2015 and a full-year loss of €6.1 billion, spurred on by restructuring and litigation costs (click here for more on this).
