Overview of Research and Education

Our main research targets are NMR analysis of proteins and peptides, development of novel production methods of heterologous proteins and peptides. Our final goals of the research are to create the artificial proteins with complete control. We also utilize NMR for metabolomics researches. Our group are conducting research on NMR metabolomics which comprehensively analyzes metabolites of living organisms in various body fluids related to health and diseases.
