Appropriate selection of patients for combination immunotherapy in HCC: the now and the next

Dr Singal is an expert in hepatocellular carcinoma (HCC), particularly in early tumor detection and screening process failures, and serves as Medical Director of the Liver Tumor Program at UT Southwestern Medical Center, USA. He has research training in Patient Centered Outcomes Research, with a Masters in Health and Healthcare Research from the University of Michigan. He currently is leading several federal and state funded projects to evaluate interventions to improve the effectiveness of early tumor detection efforts among patients with cirrhosis in the USA. Dr Singal has published over 100 scientific papers and has established collaborations with experts throughout the USA over the past several years. He has been active in many academic professional societies including American Association for Study of Liver Diseases (AASLD), International Liver Cancer Association (ILCA), American College of Gastroenterology (ACG), and American Gastroenterological Association (AGA). He was selected as Chair of the ICLA Surveillance and Biomarkers Special Interest Group and is a member of the AGA Liver Disease Measures workgroup. He has editorial experience including an Academic Editor for PLOS Medicine and an Associate Editor for Clinical Gastroenterology and Hepatology and Seminars in Liver Disease.
