Research Interests

Evolutionary Developmental Biology: Molecular development of vertebrate external genitalia; Evolution of vertebrate limb development; Developmental genetic mechanisms of vertebrate skeleton evolution.

Students Currently Supervised

GuangJun Zhang (PhD)
I am interested in the morphological novelties and their developmental mechanisms during evolution. Currently I am working on the developmental genetic mechanisms of vertebrate axial skeletal.

Ashley Seifert (PhD)
