専門は植物系統進化学です。主に陸上植物の種多様性と進化に関する研究をおこなっています。世界各地のフィールド・標本調査、形態学的手法と分子生物学的手法を主な柱に、広域分布する海浜植物やマングローブ植物などの種子海流散布型植物の分布形成過程の解明に関する研究に従事しています。また、小笠原諸島・鬱陵島・ファンフェルナンデス諸島の固有種に注目し、海洋島における植物の種分化機構の解明にも取り組んでいます。2007年には小笠原諸島南硫黄島自然環境調査に参加し、植物を中心としたインベントリ調査を行うなど、生物多様性の保全に関する基礎研究も進めています。

Koji TAKAYAMA
I am studying plant systematics and evolution. My research interests are evolutionary process and speciation that have led to the current distribution and diversity of plants. I am researching with field investigation and molecular techniques to examine biogeography of mangroves and pan-tropical plants with sea-drifted seeds, which are distributed across extremely wide ranges. I am also conducting taxonomic, phylogenetic and population genetic analyses of endemic plants on oceanic islands (Ogasawara, Ullung, and Juan Fernandez Islands), to understand speciation and diversification process of the plants. In 2007, I participated the investigation of natural environment of Minami-Iwo Island that belongs to the Bonin (Ogasawara) Islands, and conducted plant inventory research for conservation of the oceanic island flora.
