Welcome to the website of the Water Treatment (Prof. Takahiro Fujioka's) Lab in the Water & Environmental Science Program, Graduate School of Engineering, Nagasaki University, Japan. The Water Treatment Lab focuses on the development of membrane-based water treatment technologies and analytical techniques to produce high-quality and reliable recycled water for Potable Water Reuse. In addition, we are also developing low-capital/operating cost water treatment technologies for developing countries (Our Water Environment Research Activities).

MEXT scholarship program (three positions available under University's recommendation for the Water and Environment Science Program).

The Water Treatment Laboratory led by Prof. Takahiro Fujioka at the Graduate School of Engineering, Nagasaki University, Japan is seeking applicants for PhD program (Water and Environment Science Program) starting in October 2024. It is the best scholarship in Japan: the scholarship covers all expenditures including travel, enrolment/tuition fees, and living expenses (approx. $1000 USD/month) for 3 years.

The applicants need to be from countries and regions designated by MEXT (see here), and have a grade equal to or more than the B2 equivalent of the European Common Language Reference Frame (e.g., IELTS = 5.5). They also need to have a GPA (MEXT calculation) of 2.3 or higher. Even if not selected, there will be several other options (e.g. other scholarships and RA) available. 

Special notes:

Interested candidates should contact Prof. Takahiro Fujioka (tfujioka @ nagasaki-u.ac.jp) along with a CV, so that they will receive a full application guideline. The application deadline is December 20, 2023 (preferably before 15 December).
