Luis Alberto Diaz, Jr., M.D.
Associate Professor, Oncology

Luis Diaz, M.D., is director of translational medicine at the Ludwig Center for Cancer Genetics and Therapeutics at the Johns Hopkins Kimmel Cancer Center. Dr. Diaz was handpicked by Ludwig Center director Bert Vogelstein, M.D., the researcher who defined cancer as a genetic disease and whose team cracked the genetic codes for brain, breast, colon, and pancreatic cancers, to move its laboratory discoveries to the clinic.

Dr. Diaz’s clinical interests include gastrointestinal cancers including colorectal cancer and pancreatic cancer.  The focus of Dr. Diaz’s research is two-fold.  The first is translating novel and often high-risk therapeutics with unique mechanisms of action from the lab to patients. One example is using live bacteria to target and destroy solid tumors. This approach, termed bacteriolytic therapy, is being testing in clinical trials at Johns Hopkins and the University of Pennsylvania in humans and canines with advanced solid tumors. His second area of research includes a novel test that measures tumor-derived DNA in the bloodstream. The blood test, based on the unique genetic fingerprint contained within the genome of every cancer, can not only detect the presence of tumor but track its progress. The ultimate goal of this work being early detection of cancer with a simple blood test before it becomes lethal.

Dr. Diaz is also director of a new clinic for patients with metastatic colorectal cancer.  This clinic focuses on the treatment of all aspects related to these patients, including support with pain, nutrition, psycho-social issues, and access to clinical trials and cutting-edge therapies. 

Dr. Diaz received his medical degree from the University of Michigan Medical School, and completed his general medicine training at Johns Hopkins followed by a fellowship in Medical Oncology at the Johns Hopkins Kimmel Cancer Center.
