Professer / KASAI Daisuke
Prof. Kasai is always supportive of his students and regularly gives helpful advice on our research and papers.
He also encourages us to take initiative and provides opportunities to gain valuable experiences, such as presenting at conferences and joining overseas internships.

Research Content

Our laboratory focuses on the functional analysis of environmental microorganisms under the theme of “exploring, understanding, and harnessing the potential of microorganisms for environmental remediation and resource circulation.”
Currently, polymeric materials such as rubber and plastics are frequently disposed of through incineration and landfilling, practices that have led to serious environmental pollution.
To address this issue, we aim to establish sustainable waste treatment and recycling systems by elucidating the material conversion capabilities of environmental microorganisms, as well as the functional properties of their genes, enzymes, and their genomic architectures. This research will contribute to environmental remediation and the reduction of environmental burdens.

A Day in the Lab

The core working hours are nine hours per day, including 10:00–15:00 on weekdays. Students independently plan and conduct their research, and attend weekly meetings where they receive advice on research progress and guidance on problem-solving from faculty members, followed by the formulation of research plans for the following week.
In seminars, students take turns preparing and presenting slides that introduce relevant research articles written in English, thereby deepening shared knowledge and understanding within the laboratory.
In addition, research techniques are often taught by senior students to junior students, which promotes active communication among laboratory members.
