Hariharan Thangarajah, M.D., M.P.H.

Bio

Dr. Thangarajah is Section Chief of Pediatric Surgery at Rady Children's Hospital and an assistant professor of surgery at the UC San Diego School of Medicine. He is board certified in general and pediatric surgery, and a fellow of the American College of Surgeons.

He obtained his undergraduate degree from UC Berkeley and attended medical school at UC San Francisco as a Regents Scholar. Dr. Thangarajah trained in general surgery at Stanford University Medical Center. During his residency training, he pursued a research fellowship in regenerative medicine at the Stanford University School of Medicine and obtained a Master of Public Health at UC Berkeley. He went on to complete a fellowship in pediatric general and thoracic surgery at Boston Children's Hospital and Harvard Medical School. Dr. Thangarajah practiced as a staff surgeon at Boston Children's Hospital prior to moving to San Diego.

Dr. Thangarajah practices the full breadth of pediatric surgery and performs a high number of operations annually. He has expertise in minimally invasive (laparoscopic) surgery, where small incisions and a video camera are used to perform operations, leading to less postoperative pain and a faster recovery. He is the first surgeon in the San Diego area to successfully perform certain advanced pediatric laparoscopic procedures. Dr. Thangarajah has specific clinical interests in congenital anomalies, pediatric surgical oncology, hepatobiliary disease and trauma.

As a faculty member in the UC San Diego School of Medicine, Dr. Thangarajah is involved in the training of medical students, residents and surgical fellows. He is also actively involved in clinical research. His research interests include pediatric trauma, variations in the delivery of pediatric surgical care, and global health.

Dr. Thangarajah recognizes that having a child undergo surgery can be a scary and stressful time. Knowing that good communication can alleviate some of this anxiety, he spends ample time discussing the details of a procedure with patients and families, ensuring that all questions are answered. He finds nothing more rewarding than having a child return to good health after a successful operation. His care philosophy is to treat patients the way he would want his family treated.
