B.S., Tohoku University, 1995

About:
My primary research interest is applying various geochemical tracers to understand elemental cycles in lithosphere, hydrosphere, atmosphere, and biosphere. My areas of expertise include stable and radio-isotopes, sedimentary geochemistry, marine biogeochemistry, gamma spectroscopy, marine geology, petroleum geology, natural hazards, and paleo-oceanography/ -climatology/ -biology.

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.

After the 3/11 Tohoku earthquake in 2011, I attempted to determine the degree and extent of radiological contamination across Japan using gamma spectroscopy. Read these news stories (6/17/2011 and 5/10/2013) appeared in a journal called Science about radiological contamination in the Tokyo Metropolitan and NE Japan.

My current research focus is to understand the triggering mechanism of catastrophic landslides and debris flows associated with earthquakes and excess precipitation.
