My primary research interest is applying various geochemical tracers to understand elemental cycles in lithosphere, hydrosphere, atmosphere, and biosphere. My areas of expertise include isotope geochemistry, sedimentary geochemistry, marine biogeochemistry, gamma spectroscopy, marine geology, petroleum geology, and paleoceanography/paleoclimatology.
Going out in the field has been an essential part of my career as a geologist. In late 2004, I sailed on IODP Expedition 303 to the North Atlantic as a geochemist aboard the luxurious drillship JOIDES Resolution. I have also participated in ODP Leg 189 to the Southern Ocean off Australia as a sedimentologist in early 2000.
My current focus after the 3/11 Tohoku earthquake is to determine the degree and extent of radiological contamination across Japan using gamma spectroscopy. Read this Science news article (June 17, 2011 issue) about radiological contamination in the Tokyo Metropolitan.
