Research subject: Using various structural biology and biophysical techniques such as NMR and SPR, we analyze the structures and interaction of proteins and glycans to elucidate the biological phenomena they are involved in. Furthermore, we aim to control them for drug discovery.

Research interests: Anaerobic bacteria, Bacteroides, drug resistance mechanisms, whole genome analysis

Research subject: We are engaged in research on drug resistance mechanisms of Bacteroides (especially Bacteroides fragilis), an anaerobic bacterium commensal to the intestinal tract and sometimes isolated from intra-abdominal infection colonies. In particular, we aim to elucidate the mechanism of carbapenem resistance in this species using comprehensive methods such as whole genome analysis

Research subject: I am studying the mechanism of colorectal motility regulated by the central nervous system and the relationship of this mechanism to defecation disorders. It has been shown that descending pain regulatory system is involved in the central regulation of colorectal motility, so pain modulation and regulation of colorectal motility seem to share a common neural pathway. The aim of this study is to elucidate the pathophysiology of defecation disorders, such as irritable bowel syndrome (IBS), in which abdominal pain and defecation disorders coexist.

Research interests: Obligate anaerobic bacteria, phylogenetic classification, infectious disease

Research subject: The major focus of our laboratory is on the bacteriology of the obligate anaerobes that comprise the major commensal flora of humans. In recent years, advances in science and technology have led to a restructuring of the bacterial classification system. Our research focuses on drug resistance genes in especially so-called "pathogenic bacteria" that are harmful to humans. We also provide assistance in the identification of bacterial species by genetic approaches to cases from nearby hospitals and other facilities that have difficulty in determining the species of bacteria.
