Kai He is a zoologist specializing in the taxonomy, phylogeny, and adaptive evolution of small mammals, particularly Eulipotyphla. His research integrates morphological, genomic, and single-cell approaches to investigate cryptic diversity and the molecular mechanisms underlying extreme physiological traits. He is also expanding his work into AI-assisted biology, employing deep-learning tools for morphological and evolutionary inference. He currently holds a professorship at Guangzhou University, China.
