Development of Environmental DNA Analysis Techniques

We are developing and improving methods to efficiently collect and accurately analyze DNA from organisms present in the environment. Specifically, this includes optimizing filtration and preservation methods, DNA extraction processes, and standardizing analytical techniques. In addition, we are working on innovative approaches that go beyond mapping species distributions by examining factors such as the ratio of nuclear DNA to mitochondrial DNA and DNA methylation patterns. These advancements aim to enable analysis of not only the presence of organisms but also their behaviors and physiological states.

Monitoring of Rare and Invasive Species

We aims to detect endangered species and invasive species at an early stage and link the findings to conservation and management efforts. We develop species-specific detection methods using environmental DNA to efficiently identify a wide range of taxa, including fish and amphibians. Ultimately, our goal is to implement these techniques in policy and society.

Selected Publications

Biodeversity Monitoring

We monitor the species composition and abundance of aquatic organisms, such as fish, inhabiting rivers, lakes, and coastal areas to assess the current state of ecosystems and track changes over time. By applying environmental DNA metabarcoding and quantitative eDNA analysis, we contribute to both short-term and long-term ecosystem monitoring.

Selected Publications

Ecology of Infectious Diseases

We investigate how pathogens are distributed in aquatic environments. By detecting pathogens using environmental DNA, we assess public health risks and contribute to the prevention and management of infectious diseases. Another important research focus is the inflow and spread of antimicrobial-resistant bacteria in water systems.

Selected Publications

Urban Ecosystems and Well-being

We study how urban green spaces and blue spaces, such as parks and water bodies, benefit people’s lives and well-being. Our research analyzes the relationship between ecosystem services and human happiness, proposes policies to reduce disparities in access to nature experiences, and promotes initiatives for Satoyama restoration.

Selected Publications

Physiological Ecology of Animals

We study fish, ascidians, and insects to uncover the mechanisms of genes and proteins involved in vision and the circadian clock.　By clarifying the molecular structures of opsins functioning in the retina, as well as expression patterns of clock genes, we aim to understand how organisms adapt to fluctuating environmental conditions.
