Gates Foundation CEO Sue Desmond-Hellmann to step down after five years

By Kate Kelland

(Reuters) - The multi-billion-dollar philanthropic Bill & Melinda Gates Foundation said on Thursday that its chief executive officer, Sue Desmond-Hellmann, is to step down after more than five years, to be replaced by Mark Suzman.

Desmond-Hellmann, who until October was also on the board of the social networking company Facebook Inc <FB.O>, said she was stepping down from the Gates Foundation as of February 2020 to be able to "care properly for myself and my family."

Desmond-Hellmann was previously Chancellor of the University of California, San Francisco, the first woman to hold that position, and had worked at the pharmaceutical firm Genentech - now owned by Roche <ROG.S> - where she helped develop some of the first gene-targeted cancer drugs, Avastin and Herceptin.

"This was without a doubt the toughest decision of my career. But... one of my mantras is: take your own pulse first. Over the last few weeks and months, I have done just that and concluded that I need to slow down," Desmond-Hellmann said in a letter to Foundation employees, a copy of which was shared with Reuters.

The Gates Foundation, led by Microsoft <MSFT.O> co-founder Bill Gates and his wife, Melinda, is one of the world's largest funders of global health programmes to combat disease and poverty. It has around $50 billion in assets.

Desmond-Hellmann's successor, Mark Suzman, joined the Gates Foundation in 2007 and is currently its chief strategy officer.
