Maura McGrail

Associate Professor; Chair of Molecular, Cellular and Developmental Biology Graduate Program

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.

Research Description

The McGrail lab research focus is brain cancer genetics using the zebrafish model system. We develop novel CRISPR gene editing tools to study RB and TP53 tumor suppressor function in brain development, and understand how their loss drives tumor cell proliferation and survival.
