Richard Lawrence "Larry" Edwards is an American geochemist and Distinguished McKnight University Professor and Regents Professor at the University of Minnesota.[1] He is one of the most cited and respected geochemists in the world,[2] and is well-known for his contributions to modernizing the uranium-thorium (Th-230) radiometric dating technique.[2]
Edwards earned his Ph.D from the California Institute of Technology in 1988 after studying under Gerald J. Wasserburg.[3] His thesis, entitled High Precision Thorium-230 Ages of Corals and the Timing of Sea Level Fluctuations in the Late Quaternary, discusses the usage of Th-230 dating in the examination of corals at Santo and Malekula Islands, Vanuatu.[3]
Edwards has made notable contributions to anthropology through dating a jawbone at 100000 years old, suggesting that modern humans had inhabited the area of China where the bone was found earlier than previously thought.[4] His collaborations with geochemist Hai Cheng have led to the largest number of environmental science papers published in Nature Index journals by a pair of geochemists.[5]
