Research Interests

One sunny day in May, when I was an undergraduate student of theoretical physics, I was deeply impressed at the complexity of nature, looking at the stream of the river flowing though the city of Kyoto. Since then, my interest has been focused on fluid mechanics, which is a branch of physics on dynamics of air and water. Recent years, I have applied the theory of fluid mechanics to swimming and flying living things, in particular, to mysterious problems of sperm journey.  I would like to keep pursuing ‘simple’ questions in complex nature as I thought at the river.

Research Projects

・ Symmetry on fluid equations and deformation of swimmers

・ Similarity on swimming in different scales

・ Stability and efficiency of swimming cells with cilia and flagella

・ Sperm swimming and hydrodynamic phenomena in reproduction

・ Mathematical and computational methods for swimming problems
