Nathan Ellis, PhD

Associate Professor, Cellular and Molecular Medicine
Scientific Director, Cancer Biology Research Program
Associate Professor, Cancer Biology - GIDP
Associate Professor, Genetics - GIDP
Chair, ABBS Program
B.S.- St. Johns College – Annapolis, MD, 1979
Ph.D.- University of Washington (Genetics) – Seattle, WA, 1987
Post-doctoral Fellowship: Imperial Cancer Research Fund, London, UK 1990
Major Areas of Research Interest: 
The Ellis laboratory is dedicated to investigation of the relationship between genomic instability and cancer susceptibility. Genomic instability is a dominant feature of cancer cells, and it is the central phenotype of a large group of clinical entities in which cancer development is the main and often fatal consequence.
