Reika Yokochi
Reika Yokochi (born 1975 in Saga, Kyushu Prefecture, Japan) is a Japanese geochemist working on the origin and geological behavior of volatile elements. She currently holds the position of Research Professor in the Department of Geophysical Sciences at the University of Chicago.[1] Yokochi leads a laboratory specializing in the purification and analysis of noble gases for dating and tracing water circulation within the Earth's crust.[2][3]
Education and early career
Yokochi completed her PhD studies in earth sciences at National Polytechnic Institute of Lorraine (French: L'Institut National Polytechnique de Lorraine) in 2005, supervised by Bernard Marty.[4] Her PhD thesis focused on understanding the origin of volatile elements in Earth, and she identified the presence of noble gases of solar wind origin in Earth's deep mantle.[5] She also worked out the contribution of 244Pu-decay (t1/2=81 Myr) to fissiogenic 136Xe* in the deep Earth, suggesting a protracted loss of volatiles from Earth's mantle.[6]
Research activities
Yokochi's research focuses on noble gas geochemistry. She used noble gas radionuclides to study the age and circulation of groundwater in major aquifers worldwide, including the Nubian Sandstone Aquifer, [7][8] Floridan Aquifer,[9] and the geothermal waters of Yellowstone.[10]
Yokochi also contributed to the analysis of gases in samples returned from the Ryugu asteroid by JAXA's Hayabusa2 mission.[11][12]
Awards and Recognition
Yokochi received the Young Scientist Award from the Geochemistry Research Association of Japan in 2012.[13] She was also named a NASA Planetary Science Early Career Fellow in 2012.[14]
Personal Life
Reika Yokochi is married to Nicolas Dauphas, a fellow planetary scientist, and the couple has two children.
