Aditi Pophale, PhD Student
I grew up in Nasik, a small town in India. I went to Johns Hopkins University for my undergraduate studies where I developed an interest in studying animal behavior. I wanted to understand the ecological context of animal behavior so I worked as a Research Assistant on a Chimpanzee Habituation project on Rubondo Island National Park, Tanzania and SCUBA dived extensively in East Timor and the Andaman Islands. I returned to India to pursue my MSc. in Wildlife Biology at the National Center of Biological Sciences, Bangalore. Following this, I was a part of the Nippon Foundation-POGO Centre of Excellence training in observational oceanography, at the Alfred Wegener Institute, Germany. I am currently a PhD student interested in studying cephalopods.
Kazumichi Shimizu, Postdoc
I got my Ph.D. in biophysics and biochemistry at the University of Tokyo with a study on molecular mechanisms underlying neural development in Drosophila. In 2011, I moved to National Institutes of Health in the US, where I learned in vivo patch clamp electrophysiology that were combined with Drosophila genetics to study neural representation of olfactory sensory stimulus in the brain. From 2017, I spent three years as a research associate at the University of Tokyo, where I studied neural circuits underlying learning and memory in Drosophila using in vivo patch clamp electrophysiology and in vivo Ca2+ imaging combined with optogenetics. In 2020, I joined the Computational Neuroethology unit at OIST, fascinated by complex and sophisticated behaviors of cephalopods. My goal is to reveal neural mechanisms underlying those behaviors, utilizing a variety of electrophysiological and imaging techniques.
Tomoyuki Mano, JSPS Postdoctoral Fellow
I entered The University of Tokyo with an interest in neuroscience, but after reading the books by Richard Feynman I decided to major in physics.
After having great fun with single-molecule imaging and soft matter physics, I went to Princeton University for my master's degree where I worked on nano-particle spectroscopy.
Then my interest in neuroscience came back once again, and I conducted my PhD research in the lab of Hiroki Ueda at UTokyo.
There I worked on 3D mouse brain imaging using light-sheet microscopy, and big image data analysis using cloud computing.
Now at Reiter unit, my interest is to apply the hard-core techniques from physics and computer science to understand the complex and interesting anatomy of the cephalopod brains.
Programming has always been my passion and Zen moment, and I write codes to chill my soul.
Outside of the lab, I enjoy running, cooking, and watching anime.
Natacha Roux, JSPS Postdoctoral Fellow
Born and raised in a small town in the center of France (Vichy), I have always been fascinated by the amazing biodiversity encountered in the marine environment. Therefore, I decided to choose a career where I could study marine living organisms. I conducted a PhD at the Observatoire Océanologique de Banyuls sur mer investigating the role of thyroid hormone in a key developmental step of coral reef fishesL the metamorphosis. This project offered me the opportunity to study a biological process in an integrative way, using various methods from molecular to behavioral analysis. Now, I am happy to completely change my research field and join Dr. Reiter’s team at OIST to study the phenomenon of cuttlefish camouflage in the wild. I am excited to enter the field of computational neuroethology and to have the opportunity to investigate the masters of camouflage in their natural environment using innovative techniques such as machine learning. I am looking forward to dive in Okinawa and spend hours observing cuttlefishes in their natural habitat.
Robert Ross, Postdoc (with Pigolotti Unit)
I research the physics of growing active matter. Currently, I am trying to understand how growth influences chromatophore patterning in cephalopods. My thesis is that the same developmental processes can be funneled to different developmental outcomes by altering how the system is grown.
Makoto Hiroi, Staff Scientist (with Stephens Unit)
I was born in Nagasaki, Japan. After completing my Ph.D. in insect physiology in Japan and France (with Teiich Tanimura at Kyushu University and with Frederic Maion-Poll at INA P-G), I moved to Berkeley, California, to work in the lab of Kristin Scott. Back in Japan, I worked with Tetsuya Tabata at Tokyo University. In 2020, I came to OIST, joining Greg Stephens' Biological Physics Theory Unit and Sam Reiter's Computational Neuroethology Unit. I am interested in how animals behave and react to their environments. I want to seek mechanisms or theory underlying volitional behaviors through the quantitative analysis of collective squid behavior. Besides work, I enjoy traveling, but my favorite is cycling along the Okinawa coast.
Jeff Liner, Research Technician
I graduated from the University of North Carolina with degrees in Clinical Laboratory Science, Business Administration, and Japanese. After spending 5 years studying HIV Associated Neurological Disease in human subjects, as well as basic neuroscience working with neuronal cultures, I returned to school for a short time to begin a career in Clinical Laboratory Science. I then worked in a pathology laboratory until moving here to my wife’s home in Okinawa in 2016 to promote her career and raise our children with their hundreds of cousins. I feel very fortunate to have found a position here at OIST in Masai Lab where I worked until 2020 using zebrafish to study retinal degeneration. I am excited to now be a member of the Computational Neuroethology Unit where I hope to utilize different skillsets, work with incredibly interesting cephalopods, and gain new knowledge and techniques.
Keishu Asada, Fieldwork Technician
I am from Japan's northmost island of Hokkaido, born to Japanese and American parents. I have always had a love for wildlife, the ocean, and strange creatures especially cephalopods. I studied Marine Biology at Victoria University of Wellington in New Zealand. I washed ashore on Okinawa in 2016, where I started working as a husbandry technician for OIST under the Physics and Biology Unit, caring for octopuses, squid, and cuttlefish. In 2020 I transferred to the Cephalopod Support Team where I continued husbandry work supporting multiple research units, before moving to Reiter Unit in 2021, where I am employed as a fieldwork technician. If I could breathe underwater I would probably stay there except to get coffee and snacks.
Miyu Nambu, Rotation Student
I graduated from the University of Leeds, BSc Neuroscience. I have an interest in the origins of consciousness and rotating in the Reiter unit is a good opportunity to learn about the universality of the nervous system and the differences between species. Squid are really cool! As my rotation project, I will work on squid tissue clearing, to finding the ideal solution for squid for clearing and decolorisation.
Tojo Rakotoaritina, Rotation Student
I graduated from Waseda University with a MSc in Computer Science and Communications Engineering. My research interests lie in the application of Artificial Intelligence (AI) to problems in computational neuroscience. I’m also interested in neurorobotics which aims to realize adaptive behaviors of biological systems using neuroscience inspired model. My current rotation project in the Computational Neuroethology Unit involves pose and trajectory tracking for quantitative analysis of squid behavior using deep learning techniques.
Kostas Tsaridis, Rotation Student
I obtained my BSc in Biology from the Aristotle University of Thessaloniki in Greece. Aiming to gain a more interdisciplinary skillset, I moved to Scotland to pursue an MSc in Systems and Synthetic Biology. In 2020, I was given the amazing opportunity to travel to Japan and join OIST as a PhD student, switching my field to Neuroscience in the process. My interests primarily revolve around animal learning and behaviour. Cephalopods are fascinating organisms to study due to their unique and bizarre behaviour repertoire, but also because of the potential insights to be gained from them regarding the evolution of neural systems and cognition in general. For these reasons I’ve joined the Computational Neuroethology Unit as a rotation student, where I will be working in exploring the physiological properties of cephalopod brains. Outside of work, I enjoy playing chess (badly) and the guitar (even worse).
