Marjorie Wonham is a research associate and science writer at the University of Alberta, Edmonton, Canada. She currently splits her time among research, science and other freelance writing, and teaching. Her research focuses on the introduction, impact, and spread of invasive species. Her writing treats biology, ethics, and communication. She teaches courses in conservation biology and invertebrate zoology. Since Edmonton is land-locked, she is always looking for an excuse to spend time on the coast, preferably the left one.
