He is the director of the Neuroblastoma Basic and Translational Program and member of the KSOM Cancer Center Tumor Microenvironment Program. He obtained his Bachelor’s degree in Biomedical Engineering from Northwestern University and medical degree from University of Illinois. He completed pediatric residency and a fellowship in clinical medical ethics at University of Chicago in 2000 and subsequently worked as a research associate professor in Bioinformatics at Northwestern University. He completed his training in pediatric hematology-oncology at CHLA in 2005 prior to joining the faculty of the USC. Dr. Asgharzadeh is a physician-scientist spending about 10% of his time performing clinical duties, and the majority of his time performing research.

Dr. Asgharzadeh’s research laboratory is focused on understanding the role of the tumor microenvironment and developing novel immunotherapies for children with peripheral and central nervous system tumors, focusing primarily on high-risk neuroblastomas and medulloblastomas. His group’s first report of identification of tumor-associated macrophages in neuroblastomas and medulloblastomas has helped to better understand the role of the immune system in biology of childhood tumors. His research has also led to the development of several novel assays to identify subtypes of neuroblastomas and medulloblastomas and predict outcome.

Mark R. Frey, PhD
Associate Professor of Pediatrics (2017–2020)


Dr. Frey received his PhD in Molecular Pharmacology and Cancer Therapeutics from State University of New York at Buffalo/Roswell Park Cancer Institute. Following postdoctoral fellowships at Roswell Park (cell biology) and Vanderbilt University (intestinal inflammation and repair) and an appointment as a Research Assistant Professor at Vanderbilt, Dr. Frey was recruited in 2010 to the Department of Pediatrics/Division of Gastroenterology and Nutrition at the Keck School of Medicine of USC and Children’s Hospital of Los Angeles as an Assistant Professor of Pediatrics and Biochemistry & Molecular Biology on the tenure track. He was promoted to Associate Professor with tenure in 2017.

Dr. Frey’s laboratory’s research program is focused on the role of ErbB receptor tyrosine kinases in intestinal homeostasis and health. In particular, he is investigating how the neuregulin receptors ErbB4 and ErbB3 help maintain intestinal epithelial barrier integrity in the face of injury and inflammation. His team was the first to report a functional role for ErbB4 in the intestine, showing that it is up-regulated in response to injury and necessary for survival of colon epithelial cells in the presence of TNF. They further demonstrated that the ErbB4-specific ligand NRG4 is protective in rodent models of inflammatory bowel disease and necrotizing enterocolitis.

Amir Goldkorn, M.D.Amir Goldkorn, MD
Associate Professor of Medicine (2015–2018)


Dr. Amir Goldkorn obtained his bachelor’s degree in biology at Harvard University and his medical degree and internal medicine training at UCLA.

Dr. Goldkorn was recruited from UCSF to USC in 2007 as a physician-scientist in the field of oncology. He has built a laboratory-based research program focused on developing the therapeutic and prognostic potential of circulating tumor cells, cancer stem cells, and telomerase; areas that offer unique opportunities to better understand and treat cancer. Dr. Goldkorn’s research has been supported by multiple NIH grants, published in high-impact journals, and honored with several awards, most recently the American Federation for Medical Research’s Outstanding Investigator Award. At the same time, Dr. Goldkorn continues to provide care for cancer patients in the hospital wards and to mentor students and house-staff in the classroom, laboratory and clinic. In addition, Dr. Goldkorn recently founded and directs a first-of-its-kind Circulating Tumor Cell Research Core at USC Norris Comprehensive Cancer Center, which received an outstanding NCI review and facilitates new research collaborations with colleagues at USC and beyond.
