Matthew James Ellis, PhD

  • Recruited to: Baylor College of Medicine
  • Recruited from: Washington University
  • Award: Established Investigator

Dr. Matthew Ellis, a clinician scientist in genomics and molecular profiling of breast cancer, is a native of the United Kingdom. He graduated from Queens’ College & School of Clinical Medicine at the University of Cambridge in England and earned his PhD at the Royal Postgraduate Medical School and Imperial Cancer Research Fund at the University of London.

Following a medical oncology fellowship at the Lombardi Cancer Center at Georgetown University in Washington, D.C., Dr. Ellis served as an assistant professor there until moving to Duke University in 2000. From 2003 to 2014, he was a professor of medicine and section head of breast oncology at Washington University School of Medicine in St. Louis. At Baylor College of Medicine, Dr. Ellis serves as the Director of the Lester and Sue Smith Breast Center and holds the C. Kent Osborne Chair of Breast Oncology. 

Dr. Ellis has dedicated his research to the study and profiling of breast cancer and has made major findings on understanding how individual mutations affect tumor behavior. He’s a member of the Cancer Genome Atlas study, which has been mapping genetic changes in common cancers, and is working to establish a connection between those changes and possible treatments. Dr. Ellis and his research team discovered that there are at least four types of breast cancers, and that each requires the development of a specific therapeutic approach.
