Professor / OHTA Tomoko
Professor Ohta is a specialist in geochemistry, focusing on environmental radioactivity and groundwater dating to understand chemical circulation in nature. Beyond her research, she is a very kind and student-oriented professor who is always approachable. She patiently answers basic questions and provides valuable advice on daily life and career paths, creating a supportive environment for all members of the laboratory.
Research Content
We aim to contribute to issues such as water resource conservation/development and radioactive waste disposal by conducting groundwater dating development and future prediction of nuclides in the environment.
1)Water resource conservation and development We are developing a groundwater dating method for groundwater flow evaluation, which is the key to water resource development and safety evaluation of radioactive waste disposal.
2)Radioactive waste disposal We are elucidating the dynamics of nuclides in forests and groundwater through research on the circulation of anthropogenic pollutants and the prediction of their distribution in the environment.

Scenes from our fieldwork
A Day in the Lab
Our laboratory has no core hours and consists of one faculty member and ten students. Since you can manage your own schedule, it is easy to find dedicated time for job hunting or personal hobbies. However, because research progress depends on each individual, a high degree of self-discipline is required. We are also a close-knit group that enjoys local traditions, such as going out for Hegi-soba or watching the Nagaoka Fireworks together. With students from diverse academic backgrounds, even those new to this field can feel comfortable. If you are interested, please join us!
