LecturerMy research in mass spectrometry-based forensic toxicology focuses on analyzing the behavior of drugs in postmortem specimens and elucidating the biochemical changes that occur after death. In particular, I investigate postmortem metabolism and search for novel biomarkers for insulin and nitrite poisoning, both of which are often difficult to detect and determine as causes of death due to postmortem alterations.
Recent Topics of Interest:
In recent years, I have also conducted chemical analyses of the odor associated with death and engaged in collaborative research in clinical toxicology.

Professor / DeanAs a lifelong endeavor, I am researching why living organisms require metals for survival, as well as the differences between metals that are essential to life and those that are not. Given that cells contain only trace amounts of metals, I am also developing analytical techniques to measure these metals with high sensitivity. Recently, my research has expanded to analyze not only metals but also a wide range of metabolites.
Recent Topics of Interest:
As biochemistry is the field of study that elucidates the chemical processes related to life and living organisms, necrochemistry can be defined as the study of the chemical processes that originate from the death of organisms. In this context, I am tackling themes in the field of forensic toxicology, such as the transformation of substances within the body after death, and how pharmaceuticals ingested before death or environmental chemicals to which one was exposed change after death (postmortem metabolism).

Assistant ProfessorMy research revolves around the exploration of functional natural products by integrating chemical biology and omics analysis. The study aims to clarify the physiological functions of secondary metabolites produced by plants and microorganisms. This investigation seeks to understand how these compounds contribute to the life cycle of the producing organisms, shedding light on their roles and functions. Ultimately, the goal is to uncover novel ways of utilizing the untapped potential of such compounds.

Assistant ProfessorMy research is focused on the development of novel radiopharmaceuticals. Radiopharmaceuticals are medications that contain a radioisotope within their molecular structure. When administered to patients and accumulated in cancer cells, radioactive radiations emitted from tumors can be used for nuclear medicine diagnostics and therapies. Since radiation is constantly emitted in the body, I aim to develop safe radiopharmaceuticals that selectively target cancerous tissues without accumulating in non-cancerous ones.
Recent Topics of Interests:
Therapeutic nuclear medicine using astatine-211 based radiopharmaceuticals and the coordination chemistry of metallic radioisotopes

Assistant ProfessorInterestingly, the Japanese word for medicine, ‘kusuri,’ spelled backwards becomes ‘risuku,’ which sounds like ‘risk.’ To me, this serves as a reminder that medicine and the risk of side effects are inherently linked. My research aims to prevent adverse effects from occurring unpredictably by visualizing risk based on drug behavior within the body and uncovering the underlying mechanisms. Through this endeavor, I hope to contribute to the development of safer, more trustworthy medical care for all.
