Biography

After obtaining his MD degree from the Autonomous University Barcelona, Dr. Llor trained in basic research and Internal Medicine at the University of Chicago and completed his GI fellowship at the University of Illinois at Chicago. He complemented his training with a PhD degree in molecular biology from the University of Barcelona. A clinically active gastroenterologist, Dr. Llor’s research and clinical interests relate to colorectal cancer. He has a very active basic and translational research program mainly focusing on two different aspects of colorectal cancer: hereditary and familial forms, and disparities in colorectal cancer. This work has resulted in almost 100 scientific publications in this field. He has made seminal contributions to the field of Lynch syndrome diagnosis as well as in the definition of other non-polyposis syndromic colorectal cancer cases. Some of his most recent work is providing important clues to the understanding of the biological differences that contribute to disparities in colorectal cancer.

He is commonly invited to lecture in colorectal cancer genetics in the US and abroad.
