My study

[Picture]

Planktonic foraminifera
(Neogloboquadrina acostaensis)
(picture width : 0.2mm; scanning electron microphotograph)

I am a specialist of Geology and Paleontology especially on Miocene planktonic foraminiferal biostratigraphy.

I am a member of AGU, Cushman Foundation for Foraminiferal Research, the Geological Society of Japan, the Palaeontological Society of Japan, the Japanese Association for Petroleum Technology and the Seismological Society of Japan.
