GERD

Dr. Parakrama Chandrasoma was born in Sri Lanka and received his medical education and initial pathology training in the Medical School of the University of Sri Lanka. He has postgraduate degrees in internal medicine, including the M.D. (Sri Lanka) and Membership of the Royal College of Physicians (UK). He immigrated to the United States in 1978. Upon completing his pathology residency, he assumed duties as Chief of Surgical Pathology at the Los Angeles County + University of Southern California Medical Center He has held this position since. After an initial interest in neuropathology, Dr. Chandrasoma joined Dr. Tom DeMeester’s Foregut Surgery team as pathologist in 1991. This led to a productive study of gastroesophageal reflux disease spanning 16 years and resulting in the development of numerous original concepts relating to the pathogenesis of gastroesophageal reflux disease. Dr. Chandrasoma has written over 140 peer reviewed papers and 6 previous pathology textbooks, including a general text on Gastrointestinal Pathology and a text on Gastroesophageal Reflux Disease, and is a Professor of Pathology at the Keck School of Medicine at the University of Southern California.
