I have studied life history of freshwater and estuarine goby. Goby is a highly diverse fish taxon and their life history is also very diverse. The fish I hold in the photograph is one of the biggest goby species in Okinawa, and the smallest species matures at 1 cm. Most of these species migrate between streams and the sea and could be transported to other streams and/or islands during the marine pelagic larval phase. Such “migration” and “larval dispersal” are foci of my research. I am working at OIST with gobies from 2008, but the goby work is endless. I hope to dig into their life history strategies more at this unit. (Researchmap: LINK)

I am a marine conservation ecologist interested in the importance of young developmental stages (larvae and juveniles) in fish population maintenance. My postdotorate at OIST will aim at understanding the relationship between pigmentation, a striking aspect of metamorphosis and highly plastic trait in fish, and environmental factors. I love the ocean and spending my time in water, which makes my work a real passion. I also enjoy travelling, good food, yoga and all outdoor activities.

I grew up in Costa Rica, where I soon fell in love with tropical rainforests and coral reefs. After completing my undergraduate studies in biology, I went to Saudi Arabia to pursue a masters and PhD degree in marine molecular ecology. Now, for my postdoc at OIST I will investigate the role of hormones in local adaptation of reef fish in French Polynesia. Although I love spending my time in the water, I have also come to enjoy being in the lab and working with data. I like travelling and trying new foods, I can’t wait to explore Okinawa!

I have studied the ecology of anemone fish (population dynamics, community structure, coexistence mechanisms etc.) in the Ryukyu Islands. Currently, I would like to reveal the relationship between the territorial (aggressive) behavior of anemonefish and the color pattern of coral fish. Also, I am interested in species recognition of anemonefish.

I spent my childhood in New Zealand, where I developed a fascination for the natural world and marine life. Upon completing both my BSc and MSc at the University of Auckland, I moved to Australia to undertake my PhD in the Visual Ecology Lab at the University of Queensland. My PhD used anemonefishes as a model for studying reef fish colour vision and visual communication. For my postdoc at OIST, I am investigating the ultimate and proximate drivers of colour pattern diversity in anemonefishes. Most of my work is aquarium and laboratory based, and employs a multi-technical approach to study variation in the white bar pattern of anemonefishes. I enjoy playing guitar, board games, and computer games.
Dr. Saori Miura, Lab Manager

I majored in Marine and Environmental Science and completed my PhD at the University of the Ryukyus. I was fascinated by the cute appearance of anemonefish and interested in the diversity of life history strategies of anemonefish. Starting with my love for anemonefish, I was fortunate to pursue physiological research on anemonefish Amphiprion clarkii for six years. And then, most of all, I would be more than happy because I can be involved in research on clownfish as a Lab manager at this unit. Personally, I love the sea, and good food from around the world. I also enjoy cooking, camping, and traveling.

I am a marine biology technician and my main duty is to support our projects involved with fieldwork at the ocean. Born and raised in Okinawa, I am very grateful to be involved with these projects challenging to the mystery of life in this local water. I believe that the outcomes will also contribute to the understanding and conservation of Okinawan unique reef ecosystem, which is precious resource for all of us living in this islands. After graduating from the University of Hawaii with marine biology major, I had been working in seafood industry particularly with tuna for the longest time. My favorite pastimes are surfing, traditional Karate, and reading.

"Horas" means "hello" in Sumatran. I was born and raised in Medan, North Sumatra, Indonesia. I have been in Japan since 2007. Despite having a Political Science and English Literature background, I am fascinated by the more tangible Marine science, mainly Clownfish and Anemones. Why do clownfish have their habitat in poisonous anemones? The anemones protects the clownfish from predators and provides food scraps. In return, the clownfish uses its bright colors to lure fish into the anemone, where they are killed by the anemone's poison and eaten. The clownfish also fertilizes the anemone with its feces. And there are many other mysteries in this relationship that really interest me. Other than that, I am also fascinated by the freshwater ecosystem. In February 2022, I join and worked for the Marine Eco-Evo-Devo Unit (Vincent Laudet) to gain a better understanding of the role of hormones in the evolution of life history strategies from an ecological, evolutionary, and developmental standpoint. My main activity outside of the lab is playing Basketball. I'm also keen to take up sea kayaking and fishing in Okinawa.

My name is Rio Kashimoto and I am a PhD student in Marine Eco-Evo-Devo unit – Pf. Vincent Laudet. During my PhD, I will study genetic perspectives for clown fish hosting giant sea anemone live in Okinawa. I have investigated the occurrence of duplication of fluorescent protein gene in 18 species of coral genomes in Marine Genomics unit- Pf. Satoh (Co-supervisor). From an early age, I hoped to have a career in (Zoological & Medical) science and evolution. In 2019, I graduated from my master’s degree at Kyoto Prefectural University of Medicine, majoring in Oncology. I am especially interested in understanding and applying genomic novelties that explain the evolutionary success of symbiotic organisms, an important theme behind my PhD theses.

After obtaining my masters in coastal and marine biology and ecology from the University of Salento in Italy, I came to this beautiful island to get my PhD. In this unit I’m studying phenotypic plasticity in anemonefish pigmentation, mainly focusing on Amphiprion clarkii, the most abundant (and most beautiful) anemonefish species around Okinawa-jima. I will use a combination of genetic, ecological and physiological approaches to understand the mechanisms behind the pigmentation polymorphisms. In my free time I love spending my time in the sea or hiking in the forests and exploring new places.

My research interests revolve around the impacts of humans on marine environments. I have an undergraduate degree in geosciences from the University of Edinburgh and a master’s degree in ecology and evolution from ENS in Paris. As part of my previous studies, I studied the hydrogeology of Niijima in Tokyo Prefecture with the University of Tokyo, looked at marine protected area assessment in New Caledonia, and worked on coastal changes and fish population in French Polynesia… I love doing fieldwork in warm water and beautiful places! For my PhD, I will investigate the impacts of human presence and pollution on fish development during early life stages in temperate to tropical settings. In my free time, I am looking forward to joining a few student associations, playing music, baking cakes, and exploring Okinawa on land and underwater!

I am from Glasgow, Scotland where I did an undergraduate degree in marine and freshwater biology. I then went to Plymouth in the southwest of the UK for an MRes in applied marine sciences. This helped me realise I will never ever be a physicist, and much preferred the idea of subtropical temperatures to swimming in the (near) freezing UK sea. So I have come to Okinawa to get a PhD in marine ecology - I will be studying pigmentation-based recognition in anemonefish, particularly carrying out behavioural experiments using mutant anemonefish with unusual colour patterns.

I am a 5th year PhD that transferred to the Laudet Unit in November 2020. Although most of my work has been on snake venom evolution, in the Laudet unit I will use comparative genomics and transcriptomics to understand the evolutionary origins of pigmentation in fish. This shift is exciting because I can apply the skills I've developed during most of my PhD on a new study system. I am also hoping to make a move to evo-devo and study metamorphosis in fish. Looking forward to a most fruitful and inspiring time in my new home as a researcher .

I am a developmental biologist interested in endoderm and gut tube development. Having worked on this topic in mammalian embryonic stem cell models during all of my postgraduate studies, it is with a lot of excitment that I now turn to clownfish! My postdoctoral project here in the lab focuses on the transformation of the digestive tract of clownfish larvae as they undergo metamorphosis, and on the role of thyroid hormones in coordinating this process. In collaboration with other labs here at Academia Sinica, I am more generally studying gut metamorphosis across the tree of life. I am an advocate for intersectional open science, preprinting, and knowledge equity, and a strong critic of the current politics of publishing in academia. Aside from my work, I am interested in data communication and visual storytelling in developmental biology.
