RUSSELL J. HEMLEY, born on 26 October 1954 in Berkeley, California, is a US citizen.

Senior Staff Scientist at the Geophysical Laboratory of the Carnegie Institution of Washington, since 2003 Director of the Carnegie/DOE Alliance Center (CDAC).

He received his BA (1977) from Wesleyan University, his MA (1980) and his Ph.D. (1983) from Harvard University. After a post-doctoral fellowship in theoretical chemistry at Harvard (1983-1984), he became a Carnegie Fellow (1984-1986) and a Research Associate (1986-1987) at the Geophysical Laboratory. In 1987 he was appointed as a Staff Scientist at the Geophysical Laboratory, Carnegie Institution of Washington. He was Visiting Professor at the Johns Hopkins University (1991-1992) and at the École Normale Supérieure, Lyon (1996, 1999).

Among his honours and memberships in professional societies we would mention the Hillebrand Medal of the American Chemical Society (2003) and the Mineralogical Society of America Award (1990). In 1997 he was elected as a member of the American Academy of Arts and Sciences and in 2001 as a member of the US National Academy of Sciences. He has been a member of the Phi Beta Kappa Society (since 1977), and Fellow of the Mineralogical Society of America (1990), the American Physical Society (1996) and the American Geophysical Union (1997).

He has lectured at virtually every major university in North America, Europe and Japan, organized successful international courses and symposia, and has collaborations with international laboratories and institutes throughout the world, including Europe’s first Centre for Science of Extreme Condition at Edinburgh.

Russell J. Hemley has published more than 430 papers, of which approximately 100 have been in high impact journals such as Science, Nature, and Physical Review Letters. He has edited four books, one of which, Ultrahigh-Pressure Mineralogy, Reviews in Mineralogy, Vol. 37, Washington, D.C., Mineralogical Society of America, 1998, is the standard reference on high-pressure mineral physics. He has also spearheaded new methods for the synthesis of diamond and has seven patents (awarded and pending) related to diamond and superhard materials.

 

HO-KWANG (DAVID) MAO, born in Shanghai, China, in 1941, is a US citizen.

Senior Staff Scientist at the Geophysical Laboratory of the Carnegie Institution of Washington.

He received his BS from the National Taiwan University, Taipei (1963), and his MS (1966) and Ph.D. (1968) from the University of Rochester. In 1968 he became Postdoctoral Fellow and later Staff Member at the Geophysical Laboratory of the Carnegie Institution of Washington (since 1972). Currently he is also Visiting Professor at the Department of Geophysical Sciences and James Franck Institute, University of Chicago; Einstein Professor of the Chinese Academy of Sciences; Director of High Pressure Collaborative Access Team (HPCAT) at Advanced Photon Source; Director of National Research Center for High Pressure at Jilin University (China); Associate Director of the Carnegie/DOE Alliance Center (CDAC) and Associate Director of the high-pressure instrument (SNAP) at Spallation Neutron Source at Oak Ridge National Laboratory.

He is the recipient of the Gregori Aminoff Prize in Crystallography (2005) from the Royal Swedish Academy of Sciences, the Roebling Medal (2005) from the Mineralogical Society of America, the Arthur L. Day Prize and Lectureship from the US National Academy of Sciences (1990), the P. W. Bridgman Gold Medal Award (1989) from the International Association for the Advancement of High Pressure Science & Technology (AIRAPT) and the Mineralogical Society of America Award (1979). He was elected as a member of the US National Academy of Sciences in 1993, a member of the Academia Sinica (Republic of China) in 1994, and Foreign Member of the Chinese Academy of Sciences (People’s Republic of China) in 1996. He was elected as Fellow of the American Geophysical Union, the American Physical Society, the Geochemical Society in America, the European Association for Geochemistry and the Mineralogical Society of America.

Ho-kwang Mao has published about 620 scientific articles documenting the properties of Earth, planetary and technological materials at high compressions.
