Nina Salama is a Full Member of the Human Biology Division at Fred Hutchinson Cancer Research Center and Affiliate Professor of Microbiology at the University of Washington. She has delved deeply into the genomics of the stomach-residing microbe Helicobacter pylori, known to cause ulcers and stomach cancer. Her discovery of hundreds of genes unique to specific strains led to the concept of a “pan genome,” the collection of both unique and shared genes in a given species. Her group continues to study the mechanisms by which genome diversification promotes chronic stomach infection. Salama’s group has also uncovered many of the genes and molecular pathways that control the corkscrew shape of H. pylori, which influence’s the bacterium’s ability to infect its host. Her research strives to probe the host pathogen interaction on multiple scales from molecular interactions to cellular processes to behavior at both the organismal and population level (http://research.fhcrc.org/salama/en.html).
