Research Interests

My research interests are focused on developing a better understanding of the immune system within the liver. My work focuses on understanding the effects of curing hepatitis C virus on the liver's immune system. In addition, we are studying how the liver responds to bacterial and viral infections to develop a better understanding of how these infections may exacerbate underlying chronic liver disease.

Clinical Interests
My clinical interests include providing care to patients with chronic liver disease including evaluation of patients for liver transplantation and providing post-transplant care. In addition, I perform endoscopy (upper GI endoscopy, colonoscopy) and liver biopsies.

Care Philosophy
I provide comprehensive care for liver diseases to my patients. This is done with a multidisciplinary team of hepatologists, surgeons, radiologists, and interventional radiologists to provide the highest quality of care. I focus on patient education and communication with the goal that my patients develop a deep understanding of their medical condition. I also strive to provide personalized care specific to each individual patient's care goals.
