Shunsuke Utsumi, Professor
0 student voices
The Utsumi Lab studies how connections among living things come about and how they change. From the standpoint of evolutionary community ecology, which combines community ecology and evolutionary biology, the lab mainly uses plants and insects as study subjects. Combining fieldwork and experiments with genome analysis, the lab works in the familiar natural environments of Hokkaido. The research extends to points of contact with human society, such as evolution in cities, ecosystem restoration, and the relationship between forests and farmland.

Takashi Hayakawa, Assistant Professor
0 student voices
The Hayakawa Lab studies the genetic mechanisms underlying the behavior, ecology, and evolution of wild animals. By combining field observation and surveys with genome analysis, the lab studies wild animals from a genomic perspective. The animals it studies range widely, including chimpanzees, Japanese macaques, koalas, echidnas, brown bears, and whales. The lab places importance on non-invasive methods, such as collecting DNA from feces without harming the animals.

The Quantitative Ecological Genetics Lab untangles ecological phenomena surrounding plants using bioinformatics techniques. Responses to the environment and interactions among organisms in the field are complex traits that involve quantitative differences. Using omics science and statistical methods, the lab seeks to understand the genetic basis behind these traits quantitatively. The lab mainly works with plants such as Arabidopsis thaliana and Arabidopsis halleri, and with the leaf beetles that feed on them.

Kiyohito Yoshida, Assistant (Joshu)

The Yoshida Lab studies the functions of long-chain polyunsaturated fatty acids (LC-PUFAs) such as DHA and EPA. Because LC-PUFAs have many double bonds, they tend to take a bent shape and are thought to play a role in maintaining the fluidity of cell membranes. The lab aims to discover physiological functions that are not yet known and to clarify their mechanisms at the molecular level. It also carries out practical research on getting microorganisms to produce LC-PUFAs efficiently.

Kyoko Miwa, Professor
0 student voices
The Miwa Lab studies, at the molecular level, how plants respond to the soil environment in order to live. Through evolution, plants have developed mechanisms to selectively take up the inorganic elements they need from the soil and to exclude elements that are toxic. The lab focuses in particular on boron, one of the essential elements, and investigates how plants sense nutrient deficiency and excess and how they regulate transport and metabolism accordingly. Based on these findings, the lab aims to create plants that can grow even in nutrient-poor soil.

Chiaki Hori, Professor
0 student voices
The Hori Lab studies the struggle over carbon between trees and fungi in forests. Trees defend themselves against microbial attack with sturdy cell walls and antimicrobial compounds, but fungi such as mushrooms have evolved the ability to break these down. Using fungi that the lab isolates from the environment itself, together with their genetic information, the lab searches for the molecular mechanisms of decomposition and for new enzymes. The lab also pursues applied research that links its basic findings to the use of degrading enzymes and to microbial control for trees.

Kenji Washio, Assistant Professor
0 student voices
The lab seeks to understand, at the gene level, the mechanisms of living organisms that protect the global environment. It aims to develop new methods of environmental management that make use of the diverse biological functions found in nature. Assistant Professor Washio studies how plant hormones support growth in plants such as rice.

Chikako Nagasato, Professor

The Cell Culture Engineering Lab studies brown algae, including kelp and wakame, using the methods of cell biology and molecular biology. Brown algae have complex alternation of generations and reproductive modes, and they are the largest multicellular photosynthetic organisms living in water. The lab investigates how the multicellular body is built and maintained, by looking at how cells divide and how cells are connected to one another. To help sustain seaweed resources, the lab also explores conditions that promote maturation and growth by taking the life cycle through to completion.

Masahiro Nakaoka, Professor

Akkeshi Marine Station is located on Akkeshi Bay in eastern Hokkaido, and its research centers on marine ecology and biological oceanography. In front of the station lies a sea influenced by the cold Oyashio Current, along with Lake Akkeshi where eelgrass grows in dense stands, as well as wetlands, rivers, and forests. Based on field observations, the lab studies the biodiversity of eelgrass beds and kelp forests, the growth of phytoplankton, and more. Founded in 1931, it is a marine station that focuses mainly on cold-current organisms, where researchers and students from Japan and abroad stay to carry out research and training.

Norishige Yotsukura, Professor

The Kelp Lab studies the diversity of plants of the order Laminariales (kelps) and their origins. The coasts of the northwest Pacific are among the most kelp-diverse regions in the world. Using molecular biology methods, the lab investigates where Japanese kelps, which include many endemic species, came from and how they expanded their distributions. To prepare for changes in growth environments, the lab identifies the genetic characteristics of various species, and also works on conserving genetic resources and breeding highly productive industrial species. The lab is located in an annex of the Field Science Center for Northern Biosphere on the Sapporo Campus, and conducts its research using the Oshoro Marine Station in Otaru.
