Research Interests

Proper formation and growth of the calvaria is critical for the proper accommodation of the growing brain during embryonic and postnatal life. Sustained calvarial bone growth relies on fibrous joints called sutures, which simultaneously act as a barrier between neighboring bones and a source of stem cells to grow bones. In a common congenital abnormality called craniosynostosis, sutures are lost and neighboring bones prematurely fuse, limiting brain growth. In the Farmer lab, we integrate multiple animal models (i.e. mice and zebrafish) with cutting edge genomic, genetic and imaging technologies to decipher the molecular and cellular basis of calvaria development.
