Monday, June 27, 2:30 PM

Award-winning researcher, explorer, author, and speaker Lee R. Berger advocates open access science and open sourcing. He holds a Ph.D. in palaeoanthropology and his novel approach to inclusive science and open collaboration earned him recognition as a Pioneer in Science by the World Science Festival. In 2016, Time named him one of the 100 Most Influential People in the World and the National Geographic Society named him Rolex Explorer of the Year.

Currently, Berger serves as the Phillip Tobias Chair in Human Evolution and head of the Centre for the Exploration of the Deep Human Journey at the University of the Witwatersrand, Johannesburg, South Africa, and an explorer at large for the National Geographic Society.

Berger’s decades of explorations into human origins on the African continent, Asia, and Micronesia have yielded exciting results, including the discovery of two new species of early human relatives: Australopithecus sediba and Homo naledi. In 2020, the Smithsonian recognized these among the 10 most important scientific discoveries of the decade. His teams have recovered more individual hominid remains in subequatorial Africa over the last decade than were recovered in the previous 90 years.

Berger has authored more than 200 scholarly and popular works on palaeontology, natural history, and exploration. Science has featured his discoveries on its cover three times and Time, Scientific American, and Discover Magazine have included him in the top 100 science stories of the year on numerous occasions. The 2015 PBS Nova National Geographic documentary Dawn of Humanity about Berger’s discovery of Homo naledi and the Rising Star expedition garnered an Emmy nomination.

Accolades for Berger’s conservation efforts include the William T. Hornaday Award and Georgia’s Youth Conservationist of the Year. Other distinguished honors include National Geographic Society’s first Prize for Research and Exploration, the Academy of Achievement’s Golden Plate Award, and the South Africa Academy of Sciences Gold Medal. His work has brought him recognition as a fellow of the Royal Society of South Africa, Royal Geographical Society, Explorers Club, and South African Academy of Sciences. Prominent advisory positions include the chairmanship of the Fulbright Commission of South Africa, Senior Advisory Board of the Global Young Academy, and Centre of Excellence in PalaeoSciences of South Africa. A South African Ambassador for Tourism, Conventions, and Business Events, Berger has garnered humanitarian awards including the Boy Scout Medal of Honor for saving a life and Red Cross Certificate of Merit. He is the honorary national president of the South African Spelaeological Association.

Berger is a founding trustee of the nonprofit Lee R. Berger Foundation for Exploration and was a founder of the Palaeoanthropological Scientific Trust as well a founding trustee of the Jane Goodall Society of South Africa. He is director of both the Malapa site and Rising Star excavations, the latter resulting in the discovery of the largest primitive hominin assemblage in history.
