Grant Award Summary

The National Science Foundation's Division of Molecular and Cellular Biosciences awarded $622,842 to the University of Pennsylvania under the Biological Sciences program (CFDA 47.074) on May 1, 2026, for collaborative research extending through April 30, 2030. The project investigates the molecular mechanisms controlling zygotic genome activation (ZGA)—the critical transition in early embryonic development from reliance on maternal RNAs to embryo-produced transcripts. Using Drosophila (fruit fly) embryos as a model system, the research combines live imaging, genetic analysis, and genomic approaches to elucidate how cells measure the nuclear-to-cytoplasmic ratio and coordinate gene expression accordingly.

The award generates fundamental research outputs including experimental data, molecular characterization of genes responding to the nuclear-to-cytoplasmic ratio, and computational models of transcriptional control mechanisms. Beyond core research deliverables, the project produces educational and workforce development products through graduate student training in genomics, quantitative imaging, and computational biology, as well as K-12 educational outreach materials addressing basic biology and genetics concepts. Findings from this research have broad implications for understanding developmental biology and human health, with direct relevance to developmental disorders and disease mechanisms including cancer.
