Health policy expert Atul Gawande discussed topics ranging from Medicaid to maternal health at the World Economic Forum in Davos, Switzerland in late January.

Gawande, professor in the Department of Health Policy and Management at Harvard T.H. Chan School of Public Health and director of Ariadne Labs, served on several expert panels during the four-day event, which brought together more than 2,500 business, political, and academic leaders from around the globe.

One panel, titled “The Trouble with U.S. Healthcare,” featured Gawande in conversation with sociologist Arlie Russell Hochschild. Another panel — “A New Era for Global Health” — included Gawande as well as experts in business and philanthropy, including Bill Gates of The Bill & Melinda Gates Foundation.

Gawande and Gates also got together to answer questions as part of the #FacetoFace series, a collaboration between CNBC and Facebook. They talked about innovation in health care, virtual reality, and their daily routines.
