The objective of my research is to understand the role of ocean turbulence in regulating biological and chemical processes at spatial scales varying from a cm for individuals to hundreds of kilometers for coastal circulation processes and its consequences for population structure and dynamics of marine ecosystems. These studies entail investigations of larval dispersal via coastal eddies and the role of dispersal in structuring nearshore marine populations, understanding spatial distributions of marine microbes and their role in driving population dynamics of higher organisms, and understanding the influence of small-scale isotropic turbulence on feeding and mating of zooplankton and fertilization success of broadcast spawning corals. Using my skills and experience as a fluid dynamicist, I contribute 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.
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.
