Kenji Kashiwagi Associate professor

My research interests include the taxonomy and biochronology of radiolarian stratigraphy in East Asia and the taphonomy of mammalian fossils in limestone caves in central Japan. Currently, I am working mostly on shallow marine radiolarian facies around East Asia from the Jurassic to the Cretaceous period. My main research target is the Tetori group of the middle Jurassic to lower Cretaceous periods distributed in the Hokuriku region, one of the well-known marine and non-marine strata in East Asia. Other research targets are mammalian fossils from limestone caves, specifically, the fossilization of Japanese monkey fossils (Macaca fuscata) collected from a limestone cave in the eastern Toyama Prefecture of central Japan.

Hideki Kuramitsu Professor

My group’s primary research focus is the protection of water resources, targeting environmental water and soil. Our research includes developing new analytical methods through active involvement in both field and laboratory research. We are also interested in the development of bioanalytical assays and biosensors using electrochemical and photochemical techniques, particularly in the design of functionalized ligands for inclusion in electrochemically active compounds to be used in binding affinity assays conducted by dynamic monitoring. So far, we have developed a number of water treatment methods for organic pollutants based on electrochemical decomposition and anodic polymerization. We are also investigating interactions between organic pollutants and humic substances, one of the most ubiquitous natural organic compounds present in water environments. We are currently collaborating on projects with universities in Indonesia, Malaysia, and Bangladesh.

Shigekazu Kusumoto professor

My present speciality is tectonophysics, including volcanic activity, and I am interested in the formation processes of tectonic basins, collapse caldera, and lava domes. I have investigated these processes by observation, analytical studies, and numerical simulation. By collaborative studies, I have investigated the formation and/or propagation processes of dikes on the basis of fracture mechanics and the estimation and evaluation of the deformation zones of sedimentary layers and areas created by the motion of buried faults. Students in my lab have estimated subsurface structures around active faults and mud volcanos by geophysical prospecting (for example, gravity surveys) and monitored crustal movements caused by volcanic activity through geodetic surveys, including leveling and gravity. To clarify the sources of these phenomena and structures, we have used two software products in particular: ITASCA’s particle flow code (PFC), based on the discrete element method, and Ansys's ANSYS, based on the finite element method.

Yosikazu Isikawa Visiting Professor

My group studies the solid-state physics of intermetallic compounds, including compounds of rare-earth metals that form magnetic materials, superconductive materials, and semimetals under high pressure and low temperature. Our research topics include valence fluctuation phenomena, Kondo systems, heavy fermion materials, and strongly correlated electron physics. The compounds that we study are synthesized as a single crystal form by Czochralski method or flux method in our own laboratory.

  Our international students who earned PhD degrees are now working as post-doctoral scholars at Hiroshima University in Japan and the Max-Planck Institute in Germany and as professors at Shanghai University, Hangzhou Dianzi University, and the Chinese Academy of Sciences in China. We welcome students who wish to embark on similarly successful international careers.

"Gain Unique Experience in Spectroscopy Studies at the Gofuku Campus"

   Spectroscopy is one of the most powerful tools for scientific study, and spectroscopic studies are particularly popular in Japan. At the Gofuku campus of the University of Toyama (5UofT), we are carrying out several unique experiments and have achieved interesting and significant results via international collaboration. At 5UofT, spectral research involving the precision measurement of atomic and molecular spectra has provided significant direct experimental information regarding molecules for various scientific communities.

   We have measured the transition frequencies of molecules and molecular irons in the microwave range (8–340 GHz), far-infrared range (to 6 THz), and infrared range (9–12 μm), achieving precisions of better than 100, 50, and 100 kHz, respectively. Our traditional microwave spectral studies have contributed to the discoveries of several interstellar molecules. Our research in radiation mixing (microwave plus laser) has produced frequency-tunable harmonic waves. We have developed unique CO2-laser/microwave-sideband spectrometers and tunable far-infrared (TuFIR) spectrometers. Laser control of the movements of groups of molecules enables us to spatially separate the nuclear spin isomers of molecules and measure even small degrees of enrichment of spin isomers (values as small as just a few percentages) by the precision measurement of spectral line intensities. Experiments such as these have been successful in studies of the nuclear spin isomers of gaseous molecules and have yielded very interesting results. A promising experiment on cold molecules has attracted significant interest and has earned substantial financial support from the JSPS.

   Spectroscopic studies conducted at 5UofT on atoms and molecules on a microscopic level have high potential application to the astrophysics of universal systems. Research experience that a student can gain in the above-mentioned multidisciplinary studies will strongly benefit his or her knowledge and understanding by providing the opportunity to perform hands-on physical experiments and develop the skills necessary to conduct advanced research. Moreover, Toyama is convenient in traffic communication and a very nice place in which to live and work. The University of Toyama has attracted many hundreds of international researchers and students from all over the world. Welcome to 5UofT!
