Special Grant Program for International Students (October 2023)


Special Grant Program for International Students / Research Assistant Program of Graduate School of Environmental Science (October 2023)

This program will select students who can likely contribute internationally in their research field, from those applying to doctoral courses at the Graduate School of Environmental Science.
Participating in research as a Research Assistant (RA) is very meaningful to develop your research ability. Each Research Assistant must serve to achieve the objective of a research subject directed by a Graduate School of Environmental Science faculty member. The research subjects are listed below.


Maximum 3 years, with the annual extension subject to evaluation of achievements by a faculty committee.

Qualifications of application (Eligibility):

Students (mainly from developing countries) who seek admission to the doctor courses of the Graduate School of Environmental Science.
If the students of this Special Grant Program are also selected as recipients of the “DX Doctoral Fellowship”, “Hokkaido University Ambitious Doctoral Fellowship,” or similar doctoral fellowships, they must choose one of them and decline the others.

Payment Exemption / RA Allowance:

Payment Exemption: Total amount of school fees is entirely covered by Hokkaido University (i.e., entrance exam fee of 30,000 yen, admission fee of 282,000 yen, and the annual tuition fee of 535,800 yen for each of three years). RA Allowance (depending on the actual working time): Total 3 million yen (1 million yen annually for three years)
The applicant should meet travel expenses for the entrance exam .

Application Deadline

List of possible research subjects (October 2023)

Title: Removal of Anionic Contaminants in Water Using Porous Materials
Professor: Shin-ichiro Noro

Pure water is essential for human survival and its availability is vital for building a sustainable society. Effective use of groundwater is key to ensuring pure water, but groundwater contamination by anions (nitrate, perchlorate, and so on) has recently become apparent in many parts of the world. The purpose of this research is to develop porous materials showing efficient removal of anionic contaminants in water and understand a removal mechanism. A successful candidate is expected to have a Master’s Degree in Environmental Science at the time of joining and he/she is required to have knowledge of synthetic chemistry, porous materials, and fundamentals of adsorption/desorption.

Title: Developing stable heterojunction semiconductors for electron and energy harvesting
Professor: Vasudevan Pillai Biju

Energy-efficient device technologies are necessary for sustainable socio-economical development. Heterojunction semiconductors for solar energy harvesting, light emitting devices, optical detectors, quantum computing, and information storage and processing have been continuously sought to design such next-generation devices. The challenging aspect of this research is the stability of donor-acceptor heterojunctions. This research aims to develop stable electron and energy donor-acceptor heterojunction semiconductors. A successful candidate is expected to have a Master’s Degree in Chemistry when joining. Also, the candidate is required to know inorganic chemistry, materials science, surface chemistry, and fluorescence spectroscopy.
