The discovery of Higgs boson is a grand monumental achievement that leads to the completion of the “standard model"(SM) of the particle physics. However, it is suggested that the world with the structure of higher symmetry, vacuum is concealed beyond the standard model. The key to reveal such a new world is the collision experiment with the world's highest energy accelerator LHC. I am involved in data analysis for searching for new particles, development research on high-speed trigger circuit and data acquisition system for "Higher Luminosity LHC", a future project in particle physics. In addition, I am focusing on the development of radiation simulation program named as Geant 4. This is used not only in particle physics but also in the medical field such as the design and operation of radiotherapy equipment.
We are also putting emphasis on education that graduate students can leap forward as researchers and technicians in the future through research on both hardware and software.

I am mainly working on the underground experiments to study astroparticle physics. Especially, I am working the following projects; neutrino observation with the world's largest underground water Cherenkov detector: Super-Kamiokande (SK), rare event (like dark matter) search with about 1 ton of purified liquid xenon: XMASS, and Tokai to Kamioka long base line neutrino oscillation experiment (T2K experiment). I am also promoting the next generation large-scale water Cherenkov detector Hyper-Kamiokande project, which is decided to start construction in 2020. I am also working on the research and development of extremely low-radiation technology, which is indispensable for these underground experiments. In particular, I am working on assay and reduction of radioactive noble gas radon which becomes a common background in many underground experiments.
Since the nature of neutrinos and the existence of dark matter in universe are phenomena which can not be explained by the Standard Model of elementary particle physics, it is necessary to unravel their properties by experiment. Students interested in such research fields, please do not hesitate to contact me by e-mail etc. These are international collaborative researches. International students are also accepted.

My research interest is new physics search, which is present only at the energy beyond the reach of human being so far. For that I am working on the LHC (Large Hadron Collider), the highest energy accelerator in the world built at CERN. I am participating the ATLAS international collaboration. I am particularly interested in finding new physics beyond the so-called Standard Model, through anomalous behaviour of collision events by means of precision measurements on production yield of known particles, such as top quarks.
In hadron colliders where composite particle(s) are collided each other, the events of interest are hidden behind enormous amount of background produced through the Strong Interaction. It is difficult to precisely predict the amount of such background as their behaviour is “emergent” – the behaviour that cannot easily be predicted from the fundamental physics laws. For their understanding, it is important to carefully observe the nature of the experimental data. I believe the fun in research is to “discover” what the data tells us, with as little bias and prejudice, even though it is a tedious procedure.
Another fascinating feature in high energy physics is that it is truly international; you also communicate with people worldwide in a large international collaboration. You will soon notice the people in the world are not very different, although they are diverse in detail. You are an academic and cultural ambassador, why don’t you join us? We also welcome students from abroad. The applicant should have strong interest in experimental high energy physics and have graduated bachelor-level course for physical sciences in a university or an equivalent institute.

My research topic is dark matter which exists more than five times than the standard matter in the universe.
I would like to reveal the nature of this mysterious matter by the direct detection measurement.

We need new "eyes" for catching a glimpse of science frontier. The new phenomena and parameters in nuclear and particle physics are realized by measuring the particles (ionized radiation beam) in many cases. I am researching and developing new detectors for measuring that new properties using innovative ideas. Especially, I'm developing Micro Pattern Gaseous Detectors (MPGDs) using modern photolithographic technology on flexible and standard PCB. I'm also joining to the high luminosity LHC experiments for producing new detectors using MPGD technologies. We welcome students, especially, those who are interested to make "new" things and to love experiments.

When the Standard Model is completed by the discovery of the Higgs particle, I am interested in exploring physics beyond the Standard Model. In order to find the signs beyond the Standard Model, from the experimental data, I research in ATLAS, one of the biggest international collaboration, at LHC which is the world's highest energy collider in CERN.
Research topics are not only data analysis for physics, but also the operations and improvements of the current system, and the development of high-speed trigger system for the future.
Technologies of electronics and computing are important fields, and those who are interested in those state-of-the-art technical information are highly welcome.
Shall we research together?

It is more than 60 years since neutrinos were discovered, but there are still a lot of unknown properties about them. I have been involved in neutrino physics experimentally by using accelerators and the large water cherenkov detector, Super-Kamiokande. The more we investigate neutrinos, the more strange and interesting research objects we find that they are. Let’s enjoy neutrino physics with us, shall we ?

My research interests are neutrino astronomy using the Super-Kamiokande detector and a measurement of ultra-low radioactivity. Recently, I am focusing on understanding astronomical phenomenon (internal motion of star) by observing neutrinos. Specifically, I have a strong interests in a research on multi-messenger astronomy, a research to search for solar oscillation (solar g-mode oscillation) by observing a time variation of solar neutrino intensity, a research on neutrinos from solar flares to reveal a particle acceleration mechanism. In addition, we are also developing a detector for precise measurement of radioactive isotopes (Radon), which is a common background in underground experiments. If you are interested in such research, please feel free to contact me by email.
