Eiji Masunaga graduated from Tokyo University of Marine Science and Technology and received his Ph.D. in Ocean Science in 2015. He subsequently worked as a postdoctoral research fellow at Stanford University, USA, and Tokyo University of Marine Science and Technology. He joined Ibaraki University in 2016, where he is currently an Associate Professor. His research focuses on physical oceanography, with particular emphasis on coastal ocean processes. In 2022, he was a visiting researcher at Scripps Institution of Oceanography, University of California San Diego, during his sabbatical leave. He is also a member of the JSPS Transformative Research Areas (A) project, “Macro Coastal Oceanography”, and actively collaborates with researchers in Japan and abroad.

I have focused my research on physical processes in coastal oceans and their associated material transport and dispersion, using field observation approach and numerical modeling. In this research project, I aim to elucidate the processes governing material inputs from land to the ocean by seamlessly investigating the land–coastal ocean–open ocean continuum. This research spans multiple academic disciplines across the land–ocean continuum and therefore requires an interdisciplinary approach. Based on the outcomes of this research, I will assess the impacts of land-derived material inputs on marine ecosystems and ultimately contribute to a better understanding of material cycling on a global scale.
Oceanography, my field of expertise (more broadly Geoscience) treat numerous phenomena across a wide range of spatial and temporal scales as well as diverse geographical regions. Research is often divided by spatial and temporal scales and by disciplinary or regional boundaries, highlighting the need for studies that bridge these divisions. I would like to be a scientist who conducts research by integrating multiple spatial and temporal scales while also bridging different regions.
