| Research Activities |
Treatment of sewage is essential to sustain favorable environment in urban systems. Yet, we still do not know what is exactly happening in sewage treatment plants. Sewage treatment largely depends on microorganisms: we know that some of microorganisms there are very helpful for us, while others rather deteriorate performances of wastewater treatment. Yet, we still do not know very well how these microorganisms co-exist in the same place. We also do not know the exact way to unleash the power of helpful microorganisms. Further, on the earth, we still do not know what kind of microorganisms are there. Microbial ecosystems in sewage treatment plants are thus very interesting target of science. My research group is working on following topics. (1) Development and evaluation of microbiological methods for the analysis of complex microbial system in wastewater treatment plants. (2) Investigations on unknown factors that affects the composition of microorganisms in wastewater treatment plants. In our recent study, we are elucidating the impact of bacteriophages. And, as a more practical work, (3) we are working on the ecology of polyphosphate accumulating microorganisms, which take the role of phosphorus removal from sewage.

| Future Plan |
While working on the very basic aspects of sewage treatment, I want to work on sewage-related issues from a totally different aspect. In Japan, sewer systems were introduced only in the last several decades. I think it is now worth to review these systems.

| Messages to Students |
Make haste slowly. To solve environmental problems, we need to know more about our relationship with the environment.
