Dr. Alexopoulos was born in Athens, Greece, and moved to the United States at a young age. He grew up in Northern California and graduated from the University of California at San Diego with a B.S. in physics. He attended the College of Physicians and Surgeons of Columbia University in New York City for medical school, then moved to Boston, where he completed a general surgical residency at the Beth Israel Deaconess Medical Center, a major teaching hospital of Harvard Medical School. During his residency, he obtained extensive experience in complex pancreaticobiliary surgery. A strong interest in pediatric liver transplantation brought him back to Northern California, where he completed a multi-organ abdominal transplant fellowship at Stanford University, one of the busiest pediatric transplant programs in the nation.
Dr. Alexopoulos is the surgical director of kidney transplantation at Keck Medical Center of the University of Southern California and the associated program director for pediatric liver transplantation at Children’s Hospital of Los Angeles. His non-transplant interests include the treatment of benign and malignant tumors of the liver, pancreas, and biliary tree, including hepatocellular carcinoma, pancreatic cancer, and cholangiocarcinoma. His experience in split and live-donor liver transplantation allows him to perform complex non-transplant liver surgery. Dr. Alexopoulos is funded in basic science research involving the detection and analysis of circulating tumor cells in liver cancer.
