Dr. Kerlan's primary research interest includes the management of liver disease including biliary disease, portal hypertension, and hepatic malignancy. He has an interest in developing innovative procedures to diagnose and treat patients with problems related to liver donor transplantation. Dr. Kerlan has also been closely involved with the development of stent grafts to prolong the durability procedure of transjugular intrahepatic portosystemic shunts (TIPS). He and his colleagues have developed a number of innovative techniques to perform TIPS in patients with occluded hepatic veins.

Dr. Kerlan has served as a Distinguished Reviewer for the Journal of Vascular and Interventional Radiology, the American Journal of Transplantation, and Cardiovascular and Interventional Radiology. He has 202 published articles and he has written 20 book chapters, 3 books, and 5 significant publications.
