David Miller, Visiting Professor/ Ravasi Unit

Professor David Miller received his PhD from the University of Kent at Canterbury in 1980. He was a Postdoctoral Research Assistant at Bristol University between 1980 and 1982 and a Postdoctoral Fellow at the University of Adelaide between 1982 and 1984. His interests are in the molecular genetics of corals - essentially investigating the molecular bases of coral-specific biological traits and the impacts of stress and disease on these. and collaboration between Miller’s group pioneered coral molecular genetics at James Cook University, and collaboration with OIST enabled the development of genomic resources for corals. Current research interests include coral-microbe interactions (focussing on the coral side of the interaction), reproduction and regeneration in corals, and the impacts of stress at the molecular level. Adequately addressing these topics requires the availability of whole genome sequences and other ‘omics resources for corals and their associated symbionts, the provision of which is a central focus of collaboration with the units at OIST led by Tim Ravasi and Nori Satoh

I majored in Genomics and completed my PhD at the Korea Advanced Institute of Science and Technology (KAIST). After fell in love with coral reef and tropical fish, I have devoted myself to investigate how the coral reef creatures have evolved and respond to a rapid changing environments. As a Group Leader of Marine Climate Change Unit, I'm working on the front line of climate change biology to learn how tropical fish (especially fish of the Ryukyu Islands) behave and acclimate by ocean warming.

Hailing from the Blue Mountains, west of Sydney, I grew up fascinated with the Ocean and each trip to the beach was spent exploring rock pools, digging through the intertidal zones, and surfing. However, it wasn’t until after completing a bachelors in communication, and travelling abroad, that I realized I wanted to help understand and protect our oceans. This led me to James Cook University. During undergrad I became drawn to research on the future challenge our oceans may face. This resulted in me undertaking Honours by research (2016) with Prof. Philip Munday & Dr Jennifer Donelson, where I investigated the effects of CO2 and feed levels on the growth and behaviour of clownfish. Following this I went on to complete my PhD (2021) focusing on the effects of marine heat waves on the growth and physiology of reef mesopredators under the supervision of Dr. Jennifer Donelson & Prof. Philip Munday. Now having arrived at OIST (2022) in the Marine Climate Change Unit, I am excited to continue researching the effects of climate change on reef fish.

I’m happy to share my background in molecular biology, marine fieldwork, and animal husbandry as a member of the Marine Climate Change Unit. I originally joined OIST in 2016 as the manager of the cephalopod operations in Daniel Rokhsar’s Molecular Genetics Unit where I worked to pioneer the emerging laboratory model cephalopod, Euprymna berryi, and helped describe several unknown Okinawan species of cephalopods. I’m originally from Florida where I earned my BSc in pre-medicine with a focus in molecular biology at the University of West Florida. After graduating I joined Hui-Min Chung’s cell signaling laboratory as a research assistant while simultaneously becoming peripherally involved in marine science research. I’m interested in being on the leading edge of climate change research and learning more about life in the sea. I usually spend my free time doing Brazilian Jiu-Jitsu, or in the water surfing, freediving, or SCUBA diving.

I graduated from Hokkaido University at the end of 2019. When I was a doctoral student, my research focused on phylogenetic and molecular biological study on nitrogen transporters in red seaweeds. My main work here is to assist the research projects by using molecular biological techniques. I am very happy to join Marine Climate Unit and looking forward to learning new things. Apart from science, I enjoy my time with family, ping-pong, snowboarding and exploring Okinawa. Okinawa is a beautiful place to live, and OIST is wonderful place to do science.

I graduated from Ben Gurion University in Israel, with a Bachelor Degree in Medical Laboratory Science, where I did bioinformatics research, and worked at the local hospital. I then joined a material engineering lab at Penn State University. Now, I am tending to the lovely animals in the marine research labs here at OIST! Having lived a few years on this beautiful island, it has become a character in my family’s life, with its own personality and quirks. Every day, I continue my conversation with it, by exploring its hidden places.

Being at OIST allows me to enjoy the beauty of nature and the view of the ocean everyday. I love living the Okinawan chill and stress-free life. Joining the Marine Climate Change Unit, I am excited to learn new things and acquire new skills. I am responsible for making the marine fishes happy and giving these lovely creatures an enjoyable life in the world we created for them. In my free time, aside from exploring the island with my family, I like to study Nihongo, sing in karaoke and in the process, damage the eardrums of the unfortunate audience.

I graduated from San Francisco State University with my MSc in Marine Biology, where I looked at the reproductive strategy of surfperches, a unique family of fishes that give live birth. Fishes have always had a special place in my heart, and I am particularly interested in evolution and speciation in fishes. My hobbies are diving, swimming, and fishing, but I also enjoy time outside of the water and love a good laugh!

I am a PhD candidate at James Cook University, Australia, supervised by Prof. Philip Munday and Dr. Sue-Ann Watson, and collaborating with the Marine Climate Change Unit at OIST. My thesis is investigating the neurobiological mechanisms through which elevated CO2 affects marine invertebrate behaviours, focusing on squid. I completed my Bachelor of Science (Honours) in Neuroscience at the University of Otago, New Zealand. My honours project, and following work as a research assistant, focused on the neuroendocrine regulatory and molecular mechanisms underlying female-to-male sex change in sequentially hermaphroditic fish. I am interested in the intersection of neuroscience and zoology, and the role of the brain in behaviour and phenotypic plasticity. Outside of research, I enjoy craft projects including pottery, sewing and candle making. I also enjoy getting into the outdoors and camping.

My passion for ocean and research on climate change comes from experiences around the world. I've spend several months working on computational neuroscience in Lausanne, Switzerland as well as studying photoacoustics in Cambridge, UK and stem cell biology in Tsukuba, Japan during my undergraduate years at Nazarbayev University (NU) in Kazakhstan. I've then jumped into my graduate medical degree at NU School of Medicine. As part of my research training I've completed several internships in University of Queensland working on computational biology of autoimmune diseases in elderly and children. I've then enrolled in a PhD course at the SOKENDAI University, Department of Genetics in 2019 studying ancient human genomes as well single-cell RNA-sequencing in zebrafish. My current work is focused on understanding of genomic changes in tropical fish in response to ocean warming.

I graduated from the University of Minnesota with a degree in global health and pre-medicine, focusing on environmental impacts on health. During my undergraduate studies, I had an internship providing academic lessons to high school students in multiple medicine and healthcare conferences at Harvard Medical School, UCLA, and American University. Though my studies are focused on global health with prior lab experience as a research assistant at the Institute of Child Development, I have always been passionate about the ocean and marine life. Thus, I am very excited for the opportunity to learn and work in marine science research. Being from Okinawa, I am so happy to return to the island after completing my studies in the U.S. and learning more about the impact climate change has on marine life. In my free time, I enjoy surfing, snorkeling, running, reading, and spending time with my family here in Okinawa!

I have always been interested in science and the oceans and when I was 14 I decided that I wanted to be a marine biologist. I moved to Hawaii from Sweden to do my undergraduate in marine biology at Hawaii Pacific University. That is when I found my interest in coral reefs, which added to my interests in genetics and ecology of marine life. Coming from Sweden I had never seen a coral reef before and fell in love the first time I went snorkelling. After graduating I worked a bit and saved money to be able to continue studying and got accepted to the masters of science in marine biology program at James Cook University in Townsville, Australia. During my masters studies I did my masters research project on the genetics of range shifting species. This is what lead me to combine my interests in genetics and ecology with a current issue and in the end it is what lead me to find the Marine Climate Change unit at OIST. I am very excited for the opportunity to learn more and work with everyone.
