Dr. Sachiko Yoshida is an Associate Researcher in the Uehiro Center for the Advancement of Oceanography within the Department of Oceanography. She is a physical oceanographer and her research foci include ocean dynamics and large-scale circulation systems, as well as understanding changes in water mass characteristics in abyssal ocean. She is a sea-going oceanographer who collects and analyzes real-time oceanographic data. She has extensive experience analyzing trajectory data to investigate how tracers are transported in the North Pacific Basin. She is particularly focused on understanding the physical processes responsible for tracer distribution at surface- and mid-depths.

Dr. Yoshida earned a B.S. in Meteorology from Kyushu University in Japan in 2002 and a Ph.D. in Oceanography from Kyushu University in 2007.
