I obtained my Ph.D. in 2019 from the Evolutionary Biology & Ecology lab at the Free University of Brussels (ULB; Brussels, Belgium). I investigated the ecology and the evolution of the conditional use of sex in a group of phylogenetically related neotropical termites. Notably, we described the first nutritional symbiosis between termites and the endosymbiotic bacterium Wolbachia —notorious for being a master manipulator of arthropod reproductive biology.

I joined the Evolutionary Genomics Unit in November 2019 with a JSPS Postdoctoral Fellowship for Foreign Researchers. I investigate the epidemiology of endosymbiotic bacteria using a near-complete time-calibrated phylogenetic tree of South American termites. I intend to reconstruct the evolutionary history of these bacterial lineages along the termite phylogeny to determine their rates of infection/extinction and influence on termite speciation and mitochondrial diversity. Lastly, I perform comparative genomics analyses to underpin the true nature of these symbioses, either mutualistic (e.g., nutritional mutualism) or parasitic, and identify their underlying molecular mechanisms.

I am an insect evolutionary biologist who graduated from the Molecular Ecology lab at the University of Wisconsin-Madison in 2022. For my Ph.D., I studied phylogeography and adaptation of alpine ground beetles in the Sierra Nevada of California. After graduation, I worked as a postdoc studying the genome evolution of moths and butterflies at the University of Florida, looking for genes associated with ancient moth evolution. My primary research fields are population genetics, molecular adaptation, and evolutionary genomics. I joined the Evolutionary Genomics Unit at OIST in January 2024 as a postdoctoral researcher, where I am involved in a project focusing on termite genome evolution. My research goal is to bridge macroevolution (e.g., phylogeny) and microevolution (e.g., population genetics) of insects by investigating their genome evolution and molecular adaptation.

A born and raised Parisian, I completed my Ph.D. at the Sorbonne Université in collaboration with the Muséum National d'Histoire Naturelle in 2023 after an eclectic curriculum, including interests in evolutionary developmental biology, morpho-anatomy of marine invertebrates, and more recently insect systematics, phylogeny, and biogeography. My current research revolves around the way geological processes affect the spatial distribution of organisms in deep time and at larger scales, using cockroaches (now including termites!) as a model. My Ph.D. work focused on better grasping the complex origins of the biota of New Caledonia, a long-standing conundrum in biogeography, using information derived both from geological data and time-calibrated phylogenies for some of its so peculiar endemic groups, most notably its extremely diverse and relictual cockroach fauna.

In the Evolutionary Genomics Unit, I will continue to work on the phylogenetic history of cockroaches, with a focus on their global-scale biogeography and its interplay with geological processes. By using NGS data recovered from the largest taxonomic sampling possible, including a great number of old museum specimens that were previously unamenable to molecular analyses, I intend to reconstruct large phylogenies based both on traditional markers and genomic data. I am also interested in traditional taxonomy and Natural History in general, and I am more than happy to answer old questions using the cutting-edge methods employed in the Evolutionary Genomics Unit.

After completing my PhD on the evolution of social complexity in termites at the Free University of Berlin, I joined the Evolutionary Genomics Unit as a JSPS Post-doctoral Fellow in October 2025. Throughout my academic training, I carried out several internships in the fields of Evolutionary Biology and Behavioural Ecology, working with a wide range of study systems from bugs to bats. I completed both a master’s degree in Functional, Behavioural and Evolutionary Ecology at the University of Rennes, and an engineering diploma at L’Institut Agro, Rennes, France. During my studies, I developed a strong interest in the evolution of sexual selection and mating systems and became fascinated with the diversity of termite species and their ecology. Here at OIST, using both genetic and behavioural analyses, I am investigating how the mating system of termites evolved. I am also looking forward to exploring Okinawa to learn more about the islands, their culture, fauna, and food.

I am an evolutionary biologist and ecologist interested in the evolution of microbial symbiosis, with a broad interest in diverse organisms. I joined the Evolutionary Genomics Unit in April 2026 after completing my Ph.D. at the University of Tokyo, where I studied the symbiotic relationship between cockroaches and their nutritional endosymbiont, Blattabacterium.

I am currently investigating the cellular differentiation and developmental mechanisms of bacteriocytes—specialized cells that harbor Blattabacterium—in the German cockroach, Blattella germanica, to better understand the adaptations that enable multicellular organisms to maintain intracellular symbionts. In addition, I am working on the phylogeny and genomics of Ectobiidae (which includes B. germanica) to gain insights into the emergence and evolution of this globally significant pest species.

I worked this past decade at the Free University of Brussels (ULB), Belgium, in the team of Dr. Olivier Hardy, where research projects focus on plant biodiversity, primarily in African rainforests.
Since early 2021, I have been discovering the thrilling world of termites. No need to say it is a new challenge for me, a challenge that I am more than happy to undertake by joining the Evolutionary Genomics Unit. The exquisite research environment, combined with my love for Japanese culture, makes my stay in Okinawa perfect!
My humble hobbies are baking, visiting new places, and hanging out with friends.

I was born and raised in Nagoya, Japan. I obtained a master’s degree at the University of Ryukyus.

As a student, I studied the taxonomy of octocorals in Okinawa.

Initially, I used to work for marine science at OIST. Still, I wanted to challenge myself and start something new, so I joined the Evolutionary Genomics Unit in December 2024 to support microphotography and molecular experiments.

I love exploring nature, running, dogs, and sweets.

BSc in Biotechnology, Sun Yat-sen University, China.
MRes in Computational Methods in Ecology and Evolution, Imperial College, UK.
I am interested in host-microbe symbiosis and want to look into how such relationships have influenced host evolution. I studied the evolutionary genomics of mangrove trees for my bachelor thesis and did metagenomic data analysis during my master course. In the Evolutionary Genomics Unit, I am studying how termite genomes evolve in response to their gut microbiome function and composition. 

I am a Ph.D. student interested in evolutionary biology, and I am most fascinated by what genomes can tell us about the billions of years that life went through. In the Bourguignon Unit, I hope to learn how genomes evolve. For that purpose, I am excited to participate in our project that looks at how strains of Blattabacterium cuenoti, an obligate intracellular symbiont living in cockroaches and termites, gradually lost many of their genes over the last 200 million years. 

I am Anastasiia. I was born and raised in a small village in the center of Ukraine. My scientific interests mostly focus on evolutionary biology, with a background in ecology and cell biology. During my Bachelor's studies, I worked on the ecology of tree species in urban environments. During my Master's studies, I decided to focus on DNA damage in mammalian spermatozoa. My Master's research became my transition point from ecological to genetic studies, and more specifically to evolution. In the Evolutionary Genomics Unit, I examine the correlation between termite gut microbiome and diet, as reflected by stable isotope data. My free time is mostly dedicated to my cat, video games, knitting, and painting. 

As a native of Okinawa, it is a great opportunity for me to do Ph.D. at OIST!

During my bachelor's thesis, I engaged in RNA-seq of the brown algae called mozuku, a delicacy of Okinawa. In the Evolutionary Genomics Unit, I am working on low-coverage genome datasets of termite, cockroach, and their symbiotic bacteria and protists. I aim to build robust phylogenetic trees of termite gut protists and determine how they have coevolved with their termite hosts during the last 150 million years.

During my free time, I like watching movies and anime and playing piano. In addition, Karaoke is one of my favorite ways to release stress!

Hi, I'm Nanako from Nagoya, Japan. I received my bachelor's degree from the School of Agricultural Sciences at Nagoya University, where I majored in animal reproduction. I plan to study evolutionary ecology at OIST. During a rotation in this unit, I studied termite nesting behavior and its variation across environmental conditions, species, and castes.

I am an Osakan who has been in love with Okinawan oceans for years and finally made a move to live here in April 2021. Before joining OIST, I have been involved in various business industries over the past 25 years, including airline, entertainment, telecommunication, Solar PV, and other industries. At OIST, I help the Evolutionary Genomics Unit to perform research smoothly. I love spending time on the beach, in the ocean, and in my kitchen. I am so excited to join and support the team!
