Satoru Tsushima

Satoru Tsushima is a Professor in the Biophysics Department at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Institute of Resource Ecology, Germany. He also holds a secondary affiliation with the Institute of Science Tokyo (Tokyo Tech), where he collaborates closely with Prof. Koichiro Takao. His research focuses on the theoretical and computational investigation of radionuclide interactions, particularly uranyl and other actinide ions, with biological molecules such as proteins.

His research interests lie at the intersection of nuclear chemistry, theoretical modeling, and environmental radiochemistry. He employs quantum chemical calculations, particularly density functional theory (DFT), to explore redox processes, speciation, photochemical reactions, and structural dynamics of actinide complexes. A key focus is understanding how radionuclides interact with biomolecules, which has implications for nuclear waste management and environmental remediation. His work bridges experimental spectroscopy with computational validation, as seen in studies combining luminescence data with quantum chemistry.

The recent publications highlight a consistent trend in actinide speciation, uranyl reactivity, and photochemical transformations. His work integrates computational modeling with spectroscopic data to uncover reaction mechanisms involving uranyl ions, including oxygen exchange, bond weakening, and reduction pathways. These studies contribute to fundamental actinide science and inform strategies for radionuclide separation and immobilization.

Satoru Tsushima has co-authored over 115 peer-reviewed articles with significant citation impact (h-index 31, Scopus). He holds patents related to photochemical removal and extraction/separation of uranium compounds, indicating translational research outcomes. While formal student advising is not explicitly detailed, his role as a professor and active researcher suggests supervision of junior scientists and doctoral candidates.

He has collaborated extensively with international researchers from institutions in Japan, Sweden, France, Portugal, Germany, Canada, Poland, Ireland, India, and the United States, reflecting a strong global network in actinide and environmental chemistry. His work is supported by access to advanced research infrastructures at HZDR and international facilities such as the European Synchrotron Radiation Facility.
