Isotope Geochemistry, Paleoceanography, Paleoclimatology

My research targets development and application of new geochemical and isotopic, tracers in paleoceanography and paleoclimate, with particular focus on radiogenic isotope systems (Ar, Sr, Nd, Hf, Pb). Although these tracers have, been widely used in solid-earth geochemistry, they represent a relatively new, but promising suite of tracers in the low-temperature environment.

My research is centered around two main goals, which are (i) the application of, radiogenic isotopes in various archives to yield records of past glaciation, weathering, ocean circulation, and climate from millennial- to million-year, time-scales, and (ii) to achieve a better understanding of the basic processes, controlling the sources, sinks and transformations of dissolved and detrital, trace elements and their isotopes in the coupled land-ocean-atmosphere system.

Some of my projects include:

  • Paired neodymium isotope and radiocarbon analyses in deep-sea corals - A novel ocean ventilation tracer
  • Reconstruction of the Antarctic ice sheets by provenance studies of ice-rafted debris
  • GEOTRACES intercalibration of Nd and Hf isotopes and REE
  • Antarctica's geological history reflected in sedimentary radiogenic isotopes
  • Development of the paired authigenic neodymium-hafnium isotope weathering tracer from marine sediments in the circum Antarctic realm
