Rate My Professor Shin Ikegami

Shin Ikegami is a researcher affiliated with the Department of Earth and Planetary Sciences in the Faculty of Science at Hokkaido University. He completed his Ph.D. in Earth and Planetary Science at Hokkaido University from 2020 to 2025. His research centers on paleontological studies of cephalopods, employing digital fossil-mining techniques such as grinding tomography to analyze fossil records from the Cretaceous period.

Ikegami served as the first author on the 2025 paper titled “Origin and radiation of squids revealed by digital fossil-mining,” published in Science, which documented the dominance of ancient squids in marine ecosystems approximately 100 million years ago. He also contributed as lead author to research on giant octopuses as top predators in Cretaceous oceans, detailed in a subsequent Science publication. These studies highlight rapid diversification and ecological roles of early squids and octopuses based on newly uncovered fossil evidence. No additional details on prior degrees, appointments at other institutions, awards, editorial roles, or public lectures are available from official university sources or academic profiles.
