Overview of Research and Education

To decipher essence of biological phenomenon, we use multimodal structural methods including X-ray/neutron crystallography, cryo-EM, and NMR. Our targets are signal transduction pathways related to viral infection, cancer, and immunology. We are also interested in enzyme chemistry for natural product biosynthesis and RNA modification. We are required to study the basic knowledge of structural biology weekly such as Fourier-transform to apply for each project. The interests toward kinetics, thermodynamic analysis, and organic chemistry are also desired. To develop new methods for neutron crystallography is additionally underway.
