The Tezak lab is broadly interested in how the incubation environment shapes cell fate decisions and organ development. Our current work centers on gonadal sex determination and germ cell biology in reptiles, asking how embryos translate environmental cues into the decision to build an ovary or a testis. We approach these questions using classical embryology, advanced imaging, molecular techniques, and bioinformatics tools. In the Tezak lab, we value curiosity, kindness, and dedication, and we're committed to advancing science while making it accessible to all.
