معرفی
Ren Hirayama is a Professor at Waseda University's School of International Liberal Studies, specializing in paleontology with a focus on turtle evolution and fossil reptiles. His academic journey includes previous appointments as Associate Professor at Teikyo Heisei University's Faculty of Information and Lecturer at Teikyo University of Technology. With a Doctor of Science degree from Kagoshima University, Hirayama has established himself as a leading expert in vertebrate paleontology through extensive fieldwork across Japan and international collaborations.

- Doctor of Science from Kagoshima University
Hirayama's research centers on turtle paleontology, evolutionary biology, and biogeosciences, with particular expertise in Cretaceous and Miocene fossil turtles. His work integrates morphological analysis, phylogenetic systematics, and paleoenvironmental reconstruction to understand evolutionary patterns across geological time. His research has significant implications for understanding continental drift, climate change effects on species distribution, and evolutionary adaptations in marine and terrestrial environments. His field investigations span multiple Japanese prefectures including Iwate, Hokkaido, Shimane, and Chiba, revealing critical insights into ancient ecosystems.
Analysis of Hirayama's publication record shows consistent output in high-impact paleontological journals, with emphasis on turtle taxonomy (particularly Geoemydidae and Chelonioidea), Cretaceous marine reptiles, and Miocene terrestrial vertebrates. His research demonstrates interdisciplinary integration of stratigraphy, sedimentology, and comparative anatomy to reconstruct ancient environments. International collaborations, particularly with Moroccan researchers on African turtle fossils, highlight the global significance of his work in paleobiogeography.

Hirayama has secured multiple research grants from the Japan Society for the Promotion of Science, including projects on primate fauna establishment in Asia and phylogenetic positions of turtle eggshell proteins. His teaching portfolio includes advanced courses in Vertebrate Paleontology, Dinosaurs, and Science Communication, reflecting his commitment to academic training and public outreach. Hirayama actively mentors students through research projects and supervises fieldwork, fostering the next generation of paleontologists.
His laboratory work integrates morphological analysis with molecular techniques to study evolutionary relationships, while his field teams conduct systematic excavations at key fossil sites across Japan. Current research focuses on turtle evolution during the Cretaceous-Paleogene transition and Pleistocene mammal biogeography in East Asia, with ongoing field investigations in Iwate Prefecture following the 2023 discovery of a new turtle species.
