Our Team

Group members for this year and graduates
Our team members are divided into current team members and graduated members. In addition, our group actively supports those who are aiming for active in any academic or non-academic fields after acquiring more advanced expertise in a PhD programme and advanced skills in simulation techniques, visualisation and data analysis. For example, we actively utilise the following programmes to support research activities and enhance career paths: the University of Tsukuba Dual Degree Programme, the University of Tsukuba Doctoral Student Support Project, and the JSPS Research Fellowships.

JSPS Research Fellowships
The JSPS Fellowship is a system that gives outstanding young researchers in Japan the opportunity to devote themselves to research while independently choosing a research topic, etc. based on their own free ideas, and supports their research through research grants and scientific research funding.
The University of Tsukuba Doctoral Student Support Project
This is a system to provide excellent University of Tsukuba doctoral course equivalent students with benefit-type support expenses (equivalent to living expenses and research expenses).
The University of Tsukuba Dual Degree Programme
This is a programme in which graduate students enrolled in the doctoral programme at the University of Tsukuba are also enrolled in a master's programme in another specialisation and obtain their respective degrees at the same time. Three students from our group have so far obtained a PhD (Science) in astrophysics and a simultaneous MSc (Engineering) in High Performance Computing. In addition, one student is currently using this scheme to simultaneously conduct research in Dark Matter and Machine Learning.
