Hiroshi Kajihara, Professor

The Diversity Biology Ia Lab studies taxonomy, phylogenetics, and biogeography, mainly of marine invertebrates. About 1.5 million species on Earth are known, but the actual number is said to be 10 to 100 times higher. Through field surveys, collection, and experiments, together with rearing experiments, observation, and analysis in the laboratory, the lab seeks to understand the diverse and complex world of living things. The main work now underway is descriptive taxonomy and molecular phylogenetic analysis of invertebrates.

The Field Ornithology Lab studies the ecology, behavior, and evolution of birds across the Japanese archipelago, from Hokkaido to Okinawa Prefecture. Centered on fieldwork, the lab combines acoustics, statistics, molecular biology, and other approaches. The lab values walking the field in person and observing the target species closely. The lab does not feel it must keep pace with every research trend, nor does it get swept along by them; it aims to build up data that will still be valuable 100 years from now.
Tomomi Tsunematsu, Associate Professor

The Tsunematsu Lab aims to clarify the mechanisms that regulate sleep and wakefulness, and the significance of sleep. If we sleep eight hours a day, we spend a third of our lives asleep. Even so, there is still no answer to the fundamental questions of what sleep is for and why we dream. The lab focuses on using mice to clarify why and how the fantastical dreams of REM sleep occur. Launched in April 2023, this new lab uses methods such as large-scale extracellular recording, optical imaging, and optogenetics.

The Soft & Wet Matter Lab studies "gels," the materials that make up living bodies. Apart from bones and teeth, living bodies are made of water-rich soft tissue, that is, gels. By synthesizing functional gels that mimic the structure of biological tissue and examining their properties, the lab tests where the remarkable functions of living things come from. The resulting gels are also intended for application as materials useful in medicine, starting with artificial cartilage.
Hisashi Haga, Professor

The Cell Dynamics Science Lab studies how cells move together as a group and what shapes they form. Epithelial cells such as those of the skin stay firmly attached to their neighbors while moving in the same direction. The lab follows this mechanism under the microscope. It has also become clear that the stiffness and viscosity of the culture substrate, which serves as the scaffold for cells, change the shape of cell groups and the behavior of cancer cells. Bringing a physics perspective to biology, the lab investigates how three-dimensional shapes are formed and how cancer invasion works.
Toru Katoh, Associate Professor

The Katoh Lab conducts research focused on the phylogenetic relationships, genetic diversity, and genetic differentiation of insects, beginning with Drosophila. Inferring the evolutionary history of organisms from genetic variation is one of the main challenges in phylogenetics, phylogeography, and population genetics. Insects are an extremely diverse group even among living things, so studying their evolutionary history is expected to explain a considerable part of the origin of biodiversity in nature.
Kazuhiro Kogame, Project Professor

This lab studies the diversity and evolutionary pathways of algae, focusing on seaweeds and microscopic microalgae. It combines a variety of methods, including observation of morphology and ultrastructure, elucidation of life cycles through culture, crossing experiments, and molecular phylogenetic analysis. Project Professor Kogame mainly studies seaweeds, especially brown algae, and Lecturer Nakada mainly studies the green algal order Chlamydomonadales. The faculty introduction states that this is one of the few labs where students can properly learn algal taxonomy.
Kevin Wakeman, Assistant Professor

The Wakeman Lab broadly studies the diversity and evolution of marine protists, algae, and invertebrates. Its main subjects are apicomplexans that parasitize invertebrates and dinoflagellates, including species that form red tides. The lab collects samples in places such as Guam, Okinawa, and Akkeshi in Hokkaido, and studies them using data such as genomes. It accepts short-term research students (for undergraduates), master's and PhD students, and postdoctoral researchers.
Tsuyoshi Abe, Associate Professor

This lab studies the systematics of seaweeds at the Hokkaido University Museum. Focusing on the red algal genus Laurencia and its close relatives, it distinguishes species using molecular phylogeny, culture experiments, and chemical constituents in addition to morphological features. The lab also studies the seaweed flora of the northwestern Pacific, from Southeast Asia through Japan to the Russian Far East. The museum holds many seaweed specimens collected from several decades to more than a century ago, and these are also used in collaborative research in fields other than taxonomy.
Tomomichi Fujita, Professor
0 student voices
The Fujita Lab studies the developmental mechanisms and environmental responses specific to plants, and their evolution, at the level of genes and cells. It tackles questions such as why plants excel at regeneration and totipotency, and why plant cells divide almost indefinitely without becoming cancerous. Using bryophytes such as the moss Physcomitrium patens as its main study material, the lab combines molecular genetics, cell biology, and omics analysis. The Fujita Lab and the Naramoto Lab share a common research base and each admits its own undergraduate and graduate students, while the two labs cooperate in supervising them.
