Dr Jin Young Park obtained her MPhil and PhD in Epidemiology from University of Cambridge, UK. She works as a Scientist at the International Agency for Research on Cancer (IARC) of the World Health Organization in Lyon, France. Her research in the Early Detection, Prevention and Infections Branch involves a broad range of international epidemiological studies on Helicobacter pylori (H. pylori) infection and gastric cancer with the ultimate aim to search for and implement effective strategies for prevention. She is the principal investigator of large scale randomized clinical trials evaluating the role of H. pylori eradication with endoscopic follow-up in gastric cancer reduction, global gastric cancer risk factor surveys to understand the underlying burden of both exposures and outcome in a systematic way, and studies dedicated to identifying biomarkers for early detection of gastric cancer such as metabolomics.
