Dr. Isla P. Garraway is a Professor and Director of Research in Urology at the David Geffen School of Medicine at UCLA. She is a staff urologist in the Veterans Administration (VA) Greater Los Angeles Healthcare System, where she currently advises and leads efforts in the Precision Oncology Program for Cancer of the Prostate and ensuring equity with the Veterans Health Administration’s role in the presidential initiative, Cancer Moonshot.  She is a Member of the UCLA Jonsson Comprehensive Cancer Center, and Member of the Broad Center for Regenerative Medicine and Stem Cell Research. 

Dr. Garraway is a surgeon-scientist and Principal Investigator of a basic/translational science laboratory that is focused on characterizing molecular, cellular, and microenvironmental interactions associated with metastatic prostate cancer. In addition to her clinical practice within the Greater Los Angeles VA Greater Los Angeles Healthcare System, she leads several research and clinical operations projects in prostate cancer with a focus on understanding the etiologies of racial/ethnic disparities.

Dr. Garraway has received the Donald S. Coffey Career Development, Young Investigator, and Challenge Awards from the Prostate Cancer Foundation as well as awards from the STOP Cancer Foundation, and the Margaret E. Early Foundation. Her research programs are currently funded by the National Cancer Institute, the Department of Defense, the Veterans Health Administration, the Prostate Cancer Foundation, and the Jean Perkins Foundation.
