Research Area/s:
Climate/Atmospheric Sciences, Geochemistry/Petrology/Mineralogy, Planetary Sciences, Sedimentology/Stratigraphy/Paleoclimate/Paleontology
Research and Academic Interests:
Stable isotope geochemistry, with application to paleoclimate reconstruction, metamorphic & igneous petrology, atmospheric science and meteoritics.
Present work includes: triple oxygen isotope analysis of waters and sediments, chlorine, oxygen and hydrogen isotope analyses of extraterrestrial materials (meteorites, Moon and Mars), volcanic gases, and Earth's early exosphere and animal metabolism.
I have recently installed one of the first tunable infrared laser direct absorption spectroscopy (TILDAS, Aerodyne Corp.) units to measure the three isotopes of O with a 20 ppm precision.
