The Department of Biophysics consists of three major courses. In the molecular cytology course, we are studying the structure and function of proteins involved in cellular signaling and the molecular mechanisms for the control of genome information. In the integrated function course, we aim to elucidate the roles and mechanisms of synaptic plasticity in the nervous system and the molecular mechanisms of evolution and diversity of living organisms, and are conducting theoretical research on the structure and function of biomolecules. In the emergence of higher-order information course, we are studying the cellular/molecular mechanisms of vision and the morphogenesis of multicellular organisms.

Core Course

Structural Physiology

We are studying the mechanism of intracellular signal transduction by structural analysis of proteins, and the mechanism of signal transduction through membranes in the brain and nerves.


The purpose of our research is elucidating the basic principles of the mechanisms by which the brain and nerves work.

Theoretical Biophysics

We conduct theory, simulation, single molecule experimental research or molecular evolution research on the structural function of biomolecules.

Molecular Physiology

Our lab aims to clarify the molecular mechanisms of optical information conversion in photoreceptor cells and mesopic / daytime / color vision. We study the molecular properties of various proteins centered on photoreceptors from the atomic and amino acid levels.

Molecular Embryology

We are conducting research using animals such as sponges and mice to investigate animal embryogenesis, and the development and evolution of neural networks.

Genome Integrity and Control

We are studying how genome is inherited precisely to the next generation and how chromosome structure controls this inheritance system. By utilizing mammalian cells, embryos, as well as in vitro single molecule observation systems, we aim to understand these molecular mechanisms in a single-molecule resolution.

Cooperation Course

Mathematical Life Science

We analyze the behavior of complex systems of life using theoretical methods such as mathematics and computer simulation, and clarify the principles of life functions.

Biomolecular Information Science

Taking advantage of the strengths of Arabidopsis genetics and reverse genetics, we aim to elucidate the molecular control mechanism in plasticity and cell morphogenesis of plants.

Microbial Ecology & Evolution

Based on large-scale life data, we will conduct theoretical and computer science research (bioinformatics research) to elucidate the mechanism of maintaining diversity of life and the mechanism of expression and evolution of biological functions.
