Dr. Josh Neman is an Associate Professor of Neurological Surgery, Physiology & Neuroscience at the Keck School of Medicine of University of Southern California (USC). Dr. Neman is the Director of the Cancer Biology & Genomics Doctoral Program and the Scientific Director of the USC Brain Tumor. As well, Dr. Neman is the Co-leader of Neuro-oncology Disease Affinity Group and Director of Cancer Research Training and Education Coordination (CRTEC) at the USC Norris Comprehensive Cancer Center.

Dr. Neman received his doctoral degree at the UCLA David Geffen School of Medicine in Neurobiology. He then went on to complete his Cancer Biology Fellowship at the City of Hope’s Beckman Research Institute where he was a California Institute for Regenerative Medicine (CIRM) Fellow focusing on brain tumors.

As the Director of the Laboratory of Cancer Neuroscience (, Dr. Neman’s current research investigates the biology of brain metastases (cancers that spread to the brain—i.e. breast, lung, melanoma, prostate) and pediatric brain tumors. His expertise and strengths in stem cell biology and neuroscience have allowed him to develop novel molecular, cellular, and therapeutic approach to study the bidirectional interplay between the brain and cancer cells (termed cancer neuroscience). Dr. Neman’s goal is to uncover novel mechanism used by the nervous system to promote tumor growth and spread. This will ultimately result in development of improved strategies for cancer prevention and treatment of patients with these devastating diseases.

Dr. Neman has been the recipient of multiple research awards including from National Institutes of Health (National Cancer Institute, National Institute of Neurological Disorders and Stroke), CIRM, American Cancer Society, American Brain Tumor Association, STOP Cancer, METAvivor, Uncle Korry Foundation, Susan G Komen Breast Cancer Foundation, and Department of Defense.

Dr. Neman is strong supporter of involving the community in his basic and translational laboratory—this involves engaging with patients, patient advocates, and their families’. He served on the Board of Directors of Susan G Komen LA County and is involved with American Brain Tumor Association at multiple levels.
