Professor / Satoru OHTSUKA , Associate Professor / Yutaka FUKUMOTO
Both professors are very friendly and welcoming. They always enlighten the students based on academic principles and engineering best practices. Further, they help and encourage students to develop a sound engineering understanding of natural phenomena. Moreover, our professors strongly believe in freedom of expression and therefore give due importance to the students' opinions on research matters, which leads to healthy technical discussions.

Research Content

The environment disaster prevention laboratory is aimed at conducting research to solve the latest engineering challenges to prevent the catastrophic outcome of natural disasters such as earthquakes and rainstorms. Model tests and field studies are conducted to investigate the effective liquefaction countermeasures. Wide area risk assessment methodology for slopes is conducted with GIS and AI technologies against earthquakes and rainstorms (see the right figure). Moreover, stability analysis of footings is also part of the research theme. In addition, we develop particle-based numerical simulation models to reproduce the complex soil behaviors such as the deformation of sand, the internal erosion of soil and weathering of mudstone.

A Day in the Lab

Everyday in this lab is full of energy and opportunities. Students carry out their designated research activities and report its progress to the professors. Weekly group and individual seminars are conducted to keep pace with the annual research targets. All students put their best efforts into achieving their intended research goals. Preparing for the seminars is quite demanding; however, as you come to the laboratory, you feel motivated as there are colleagues who work hard along with you. Besides, Nagaoka is a peaceful city and there are activities round the year to make you feel lively such as Nagaoka fireworks.
