Dr. Donna Goldhawk is a biochemist and molecular and cell biologist, supporting molecular imaging research at Lawson. She has guided the development of a magnetic resonance imaging (MRI) reporter gene expression system, modeled on genes from magnetotactic bacteria and the magnetosome, a membrane-enclosed structure containing an iron biomineral (magnetite, Fe3O4). She has established working collaborations with physicists (Prato, Thompson, Gelman, Thiessen) and biologists (Koropatnick, Fradin, Burton) to study magnetosome-related expression in the context of cellular iron regulation and MRI.
