Hikida developed a fascination with nature from an early age, often collecting small animals and insects as a child. As an undergraduate, he studied ecology, with his graduation thesis focusing on age estimation in wood mice (Apodemus speciosus) based on their teeth. Upon entering graduate school, he shifted his focus to the phylogeny of reptiles. Since then, his research has centered on the systematics, taxonomy, and biogeography of reptiles. == Selected works ==
