Merck announced Tuesday that Chirfi Guindo will serve as the new chief marketing officer for Merck Human Health. 

In his new role, Guindo will lead the development and implementation of the company’s strategy that covers oncology, vaccines, pharmaceutical and pipeline products. 

Guindo’s hiring is the latest personnel move for the Human Health division. Effective August 1, Jannie Oosthuizen will lead the U.S. division while Joe Romanelli will lead Merck Human Health International, replacing Deepark Khanna, who is retiring at the end of the year. 

Guindo will start on July 1 and report to Merck CEO Robert M. Davis. 

“Chirfi is a purpose-driven leader, dedicated to saving and improving lives around the world. He has deep experience and a proven track record in strategy, marketing and commercialization across primary care, specialty care and rare diseases, in both developed and developing markets,” Davis said in a statement. “I am confident that our Human Health leaders, along with our entire Executive Team, will build on the strong momentum of our business as we deliver value to all our stakeholders, continue to address some of the most pressing medical challenges and make a positive and lasting impact on global health.”

Guindo previously worked with Merck for 25 years, overseeing global marketing for the company’s HIV portfolio and leading the Human Health businesses in Canada, the Netherlands and South Africa. In 2017, he became the EVP and head of global product strategy and commercialization at Biogen.
