Donald J. DePaolo is an American professor of geochemistry in the Department of Earth and Planetary Science at the University of California, Berkeley and Associate Laboratory Director for Energy and Environmental Sciences at the Lawrence Berkeley National Laboratory. Biographical summaryDonald J. DePaolo was born in 1951. He grew up in upstate New York. CareerDePaolo received his B.S. degree with Honors in Geology from Binghamton University in 1973 and earned his Ph.D. in geology with a minor in chemistry under Gerald Wasserburg at the California Institute of Technology in 1978. In the same year, DePaolo began an assistant professorship at the University of California, Los Angeles Department of Geology and Geochemistry and subsequently earned his associate (1981–1983) and full professorship (1983–1988). In 1988, he began his term as Professor of Geochemistry at the University of California, Berkeley in the Department of Earth and Planetary Science, with a joint appointment as a Faculty Scientist in the Earth Sciences Division at the Lawrence Berkeley National Laboratory (LBNL) [1]. Upon his arrival in Berkeley, Dr. DePaolo established the Center for Isotope Geochemistry, a joint research facility between LBNL and UC Berkeley [2]. In 1998, he was made the Class of 1951 Professor of Geochemistry, and served as chair of the department from 1990 to 1993. From 1998-2006 DePaolo served as Geochemistry Department Head at LBNL, in 2007 he became Earth Sciences Division Director and from 2010-2011 he served as Acting Associate Laboratory Director for Energy and Environmental Sciences before accepting the position permanently on April 1, 2011. In Spring of 2009, DePaolo became the Director of the Center for Nanoscale Control of Geologic CO2 (EFRC) [3]. Research interestsDePaolo has coauthored over 170 peer-reviewed articles and reviews. His research interests focus on using naturally occurring isotope variations to explore questions such as
Major contributionsIn his early career, DePaolo pioneered the use of samarium and neodymium isotope ratios to constrain the age and chemical evolution of rocks. DePaolo and his then advisor Gerald Wasserburg made the first Nd isotope measurements on terrestrial igneous rocks [5]. An important byproduct of this work was the development of epsilon notation (ε), with which initial 143Nd/144Nd values could be distinguished from the chondritic uniform reservoir (CHUR) in parts per ten thousand. Key principles of the Nd isotope system were laid out in his 1988 book, Neodymium Isotope Geochemistry: An Introduction. DePaolo's work has since led to significant advances in using various isotope systems to constrain rates of metamorphic processes [6], quantify continental weathering and elemental seawater budgets through geologic time [7][8], and model fluid-rock interactions [9]. As principal investigator of the Hawaii Scientific Drilling Project (HSDP), DePaolo and coworkers sampled the flank of Mauna Kea volcano to a depth of several kilometers. Major findings included a determination of the geochemical structure of the Hawaiian mantle plume [10]. DePaolo’s recent research provides a framework for understanding the partitioning of stable isotopes during mineral growth, with a focus on isotopes of calcium [11]. Recent service
