CURRICULUM VITAE

Associate Professor, Faculty of Dinosaur Paleontology
Fukui Prefectural University

Ph.D. (Science), Hokkaido University, 2011

I am an organic geochemist studying the relationships between biological organic matter and the Earth’s environment. I use organic matter preserved in sediments and fossils to reconstruct past environments and vegetation, and investigate its biological sources and geological alteration.
