Samuel Mukasa

AGU member since 1983. Past President – Geochemical Society. Currently serving as Dean and Eric J. Essene Professor of Geochemistry – College of Engineering and Physical Sciences, University of New Hampshire. Expertise is in isotope geochemistry and petrology focus on the origin of Earth’s geochemical structure, and plate tectonic evolution of the continents. Uses several research techniques, including integration of trace elements and radiogenic isotopes to model the petrogenesis of volcanic rocks, and the application of U/Pb and 40Ar/39Ar geochronology to unravel the tectonic evolution of mountain belts. BS in geology from the University of New Hampshire, 1977, MS in geology from The Ohio State University, 1980, PhD in geochemistry from the University of California, Santa Barbara, 1984. Postdoctoral Fellow – Lamont Doherty Earth Observatory (1984-85); Assistant Professor – University of Florida (1985-89); Associate to Full Professor –University of Michigan (1989-2010); Chair – Department of Geological Sciences, University of Michigan (2007-2010). 115 peer-reviewed articles (7 in AGU journals), Co-author of 2 National Academies Reports. Honors include: Elected Geochemical Society President (2010-2011); elected GSA Fellow, 2005; elected AAAS Fellow, 2006; Awarded Honorary Doctorate of Environmental Science, 2008 – Nkumba University, Entebbe, Uganda; Antarctic Service Medal, 1995; Outstanding Alumnus Award – UC Santa Barbara, 2006. Major scientific accomplishments include seminal unraveling of the kinematic effects of the Taconic and Acadian orogenies in the northern Appalachians; discovery of the short length-scales of chemical heterogeneities in the upper mantle as preserved in alpine peridotite massifs; demonstration of the chemical and physical dynamics of magma chambers that form layered mafic intrusions; and elucidation of fluid migration pathways through the mantle and crust. AGU Honors and Recognition Committee member (2013-2014); AGU Honors and Recognition Committee chair (2015-2016).
