About Me

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

We assemble a team of specialists to review each patient’s unique needs and weigh the evidence for using different therapies. Not every person needs radiation or chemotherapy, and now, more than ever before, we are able to determine quickly which therapies will be most effective for an individual. We have an innovative approach to medicine, and we offer clinical trials that provide people access to the newest therapies. Additionally, our social workers are skilled in addressing the social stressors of cancer and provide guidance to patients throughout diagnosis and treatment.

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 International Liver Cancer Association, Americas Hepato-Pancreato-Biliary Association, American Association for the Study of Liver Diseases, and the American Society of Transplant Surgeons.
