Overview of Dr. Welling

During residency, I was drawn to the specialty of hepatobiliary and pancreatic oncology—the treatment of cancers that affect the liver, gallbladder, bile ducts, and pancreas—and liver transplantation, which led me to pursue a fellowship in transplantation. I chose to focus specifically on hepatobiliary and pancreatic surgery, and today, my interest in hepatobiliary and pancreatic oncology clinical care and research continues to grow.

As director of the Liver Tumor Program, my aim is to establish a multidisciplinary approach to treating people who have liver cancer. Together, we are a team of hepatobiliary surgeons, gastrointestinal medical oncologists, hepatologists, interventional radiologists, radiation oncologists, and nurses, who collaborate to provide the highest level of care. We manage cancers that originate in the liver and bile ducts, as well as cancers that spread to the liver.

I also participate in a multidisciplinary pancreatic cancer program. We develop innovative strategies to allow more patients to ultimately undergo surgical resection.

I conduct translational research and clinical research that is primarily focused on liver cancer. I also collaborate with other researchers to identify new areas of biology to target therapeutically and ways to optimize existing therapies. The results of our recent study led to FDA approval for nivolumab, a targeted drug that shrinks liver tumors or slows their growth by activating the immune system.

I am a member of the ACS, ILCA, ASCO, ASTS, AASLD, and AHPBA.
