Staff & Research

Mark Kurz

Mark Kurz, ( current director of NOSAMS) is a geochemist whose research activities include: isotope geochemistry of mantle derived rocks and minerals, evolution of oceanic volcanoes, cosmic-ray produced nuclides in rocks and their application to geochronology, and evolution of the mantle-continent-atmosphere system.

Ann Mcnichols

Ann McNichol

Ann McNichol, staff chemist and director of the sample-preparation laboratory, is studying the distribution of 13C in oceanic DIC in order to understand the ocean’s role in the uptake of fossil-fuel-derived CO2 and to examine other processes in the carbon cycle.

Mark Roberts

Mark L. Roberts

Mark Roberts, staff physicist, is responsible for operation and continued development of both the CFAMS and US-AMS systems at NOSAMS. Research interests include AMS technology, development of gas-accepting ion sources and interfaces, and initiatives to re-determine the 14C half-life.

Karl von Reden

Karl von Reden

Karl von Reden, staff physicist (retired), founding member of the NOSAMS Facility, responsible for the Tandetron AMS operations, is interested in ion source and accelerator modeling calculations and design. Side interests are AMS radiocarbon dating of tropical wood and interaction of ion beams with nanoscale materials.

William J. Jenkins

William J. Jenkins, (retired director of NOSAMS) is a tracer geochemist whose research activities include the study of ocean circulation and ventilation, carbon and nutrient cycles, and the impact of climate change on them.

John Hayes

John M. Hayes

John Hayes (emeritus, late director of NOSAMS), maintains a program of research in isotopic biogeochemistry.
