Ives, who comes from a newspaper background, will have responsibility for the magazine's feature coverage and is planning to introduce more of a 'newsy approach' to the title.
She said: 'I am definitely looking to break some stories, find some new trends and new research that has not been covered. Things that will address the needs of women.
'We have very strong writers, good celebrity interviews and are very much about relationships - that is our selling point,' she added.
Cosmopolitan is currently defending its market-leading position (ABC 463,010 for the past six months of 2001) against the success of rival Glamour.
Ives has most recently been working as a freelance writer in New York where she covered news such as Hillary Clinton's Senate campaign and the events of 11 September, for, among others, The Daily Telegraph and the Daily Express.
