The primary objective of Professor Mitarai’s research is to understand the role of ocean turbulence in regulating biological processes and its consequences for population structure and dynamics of marine ecosystems, through international collaborations. These studies include investigations of larval dispersal via coastal eddies and the role of dispersal in structuring marine populations, understanding biological responses of corals to turbulent flows and their integrated effects on biogeochemical cycling, and impacts of tropical cyclones on particle aggregation and biological pumps. Using his skills and experience as a fluid dynamicist, Professor Mitarai contributes to a new interdisciplinary field in the marine sciences.
My research interests are focused on how microorganisms respond to heavy metal stress as well as other biotic and abiotic stress in marine ecosystems. I am currently working on two exciting projects: i) Genetic response of deep-sea hydrothermal vent Epsilon-proteobacteria to heavy metals. ii) Evaluation of plankton community dynamics and physico-chemical changes due to terrestrial runoff in nearshore subtropical waters.

Specialized in hydrodynamics numerical modeling, I have a particular interest for coastal regions and their protection. My Phd project was about Tsunami modeling and the impact of time parameters during the generation. I continue nowadays to work on this subject with the study of the tsunami that hit Ishigaki Island in 1771. I also broadened my interest by working on Mangrove propagule dispersion.
Heng specializes in experimental hydrodynamics with a focus in turbulent boundary layer flows over a rough or porous bed and their impact on sediment transport. She is currently working on flow-body interaction in a flume system under unidirectional or oscillatory flows mainly by using Particle Image Velocimetry.
My research focuses on particle dynamics and microbial activities in the ocean and investigates the impacts on marine biogeochemistry and ecology. Current projects focus on the interaction between bacteria and particles.
Working as a research assistant to support procurement and other for the research.
My research interests are focused on coastal marine conservation, especially estuary areas. As part of my research interests, my current objective is to better understand how species maintain and expand its habitat. The current project focuses on investigating temporal and spatial dispersal patterns and driving factors of mangrove species, Rhizophora stylosa. While population fragmentation negatively affect mangrove habitat, especially on island system that naturally create discrete coastal lines, the research on island systems are scarce. Using population genetic methods, oceanic numerical modeling as well as in-situ observed drifter methods will provide comprehensive understanding of dispersal patterns.
Another goal during my PhD program is to do science out-reach projects with local communities through ECO club.
Scleractinian corals constitute the beautiful coral reef ecosystems in the oceans. For some Pocilloporid corals, an escaping response called polyp bail-out can happen in stress conditions instead of bleaching, resulting in free-living, isolated, zooxanthellate coral polyps. With this response, adult solitary polyps of the same genetic background can be obtained. The objective of my PhD project is to apply this stress response to coral studies, including the emergent property of corals from solitary polyp to a coenosarc-connected colony, and the ecological role of this stress response in the scenario of global climate change.
Otis' background in marine spatial ecology brought him to the Marine Biophysics Unit where he is studying the diversity found at hydrothermal vents and how theoretical ecology and oceanographic models of connectivity can be combined to answer key questions in metacommunity dynamics and Biogeography.
My research interest is originally in animal behavior. In the interdisciplinary environment of our unit, Kota studies how marine animals respond to flow conditions. Current project focuses on investigating effects of flow speed and turbulent fluctuation on planktivorous reef fish including unique garden eels. He is running website that inform interesting fact about garden eels.

Maggi's thesis work focused on the symbiotic relationship between the haptophyte algae, Phaeocystis, and acantharian hosts ("Characterization of Acantharea-Phaeocystis photosymbioses: distribution, abundance, specificity, maintenance and host-control", Ph.D., 2020). She is particularly interested in how interactions between the smallest organisms can affect large scale processes in the ocean. Currently, Maggi is a postdoc scholar at Woods Hole Oceanograhic Institution.
