Dr. McGrail, Associate Professor, received her BS in Biochemistry from the University of Massachusetts, Amherst and her PhD in Molecular and Cellular Biology from the University of Minnesota. Her previous positions include postdoctoral work at the University of California-San Diego, Myriad Genetics in Salt Lake City, and the Huntsman Cancer Institute at the University of Utah.
The McGrail lab studies brain development and disease using the zebrafish genetic model system. We develop CRISPR gene editing technologies for functional genomics and disease modeling, with a focus on targeted integration to create genetic tools for cell-specific lineage tracing and conditional gene studies. Our research examines RB and TP53 transcriptional and epigenetic mechanisms in neural progenitor cell cycle regulation to understand how their loss drives brain tumor cell proliferation and survival. A second research area is in building novel in vivo models of neurodegeneration risk loci to investigate pathways driving neuroinflammation in neurodegenerative disease.
