Sanae has studied biology of marine mammals and plankton though her academic career. After completing her PhD on plankton ecology in the Antarctic Sea at Tokyo University of Fisheries, she worked at Japan Agency for Marine-Earth Science and Technology (JAMSTEC), where her research theme has been marine ecosystem response to climate change. She has studied mechanisms of interannual to decadal ecosystem changes in regional to basin scales using historically collected plankton data set, such as the Odate Collection. With JSPS Fund in 2009, she started taking a part in the North Pacific Continuous Plankton Recorder (CPR) Survey, which has been operated by Sir Alister Hardy Foundation of Ocean Science (SAHFOS) since the early 2000s. She has been a member of The Global Alliance of CPR Survey (GACS), which was established in 2011 aiming the global scale comparison and assessments of marine ecosystem changes.
Sanae is currently a member of several international ocean science initiatives such as IOC/UNESCO-Global Ocean Observation System Biology/Ecosystem Panel (GOOS-Bio/Eco), MONITOR committee of the North Pacific Marine Science Organization (PICES), and Group of Experts of the 2nd Process of United Nations World Ocean Assessment.
Sanae is currently working at UNEP-World Conservation Monitoring Centre (WCMC) as a Senior Programme Officer of Marine Programme since 2016 under a secondment agreement with JAMSTEC. With a long career in the area of marine biology and working experience in the international ocean observation community, her tasks are to support existing projects and contributes to the development of new projects of WCMC on linking marine science to decision making through development of global marine ecosystem indicators in collaboration with key partners.
