Eco-developmental Interactions of Craniofacial and Brain Anatomy

New York Institute of Technology College of Osteopathic Medicine (NYITCOM), has been awarded a prestigious Faculty Early Career Development Program (CAREER) grant by the U.S. National Science Foundation, supporting a five-year prize totaling $710,855. The funded project, titled "Evo-Developmental Interactions of Craniofacial and Brain Anatomy," pursues an integrated investigation of how brain and skull interact across two complementary timescales: the deep evolutionary scale spanning millions of years and the immediate developmental scale covering the days and weeks before birth. By directly linking evolutionary morphological change with embryonic and fetal developmental processes, the project aims to produce the most comprehensive study to date of brain–skull interactions across these timescales.

This work combines traditional approaches with advanced techniques to interrogate the structural and developmental relationships between craniofacial anatomy and the brain. On the evolutionary side, the project will examine long-term patterns of co-variation between skull and brain form to understand how evolutionary pressures and constraints have shaped their joint morphology. On the developmental side, the research focuses on proximate mechanisms in late embryonic and early fetal stages that produce brain–skull interactions, with attention to the days and weeks immediately preceding birth. The synthesis of macroevolutionary perspectives with developmental biology is intended to reveal how processes operating at very different temporal scales interact to produce both normal anatomical outcomes and pathological conditions.

The central motivation for this integrated research is translational: a better mechanistic understanding of brain–skull interactions could inform prevention and treatment strategies for neurological and cranial birth defects. Such defects can have severe consequences, including developmental delays, physical disabilities, and mortality. By elucidating the evolutionary context and developmental mechanisms that underlie craniofacial and brain anatomy, Watanabe's project seeks to identify factors that increase vulnerability to congenital cranial conditions and to suggest pathways by which clinicians might intervene. The research thereby bridges basic science in evolutionary morphology and developmental anatomy with clinical relevance to human health.
