Research interests

Mayumi Seto is Assistant Professor in Mathematical Biology Group. She received her M.A. in Science of Resources and Environment at Tokyo University of Agriculture and Technology, and completed her Ph.D in Earth and Planetary Sciences at Kyushu University. She did post-doctoral studies at Ehime University and at National Institute for Environmental Studies. Her researches on mathematical models are aiming (1) to clarify the role of microorganisms in material cycles, and following changes in physico-chemical conditions; (2) to establish better environmental risk assessment of chemical pollution.
