About me
Dr. Kathleen M. Nilles treats adults with a range of liver conditions, including viral hepatitis, autoimmune liver disease, metabolic liver disease, alcohol-related liver disease, and inherited liver disease, as well as cirrhosis with complications of portal hypertension, liver disease related to cardiac disease, and patients with benign and malignant liver lesions. In addition, she provides care to patients awaiting liver transplant as well as to patients who have received a liver transplant. She also evaluates people who are interested in becoming living liver donors.
She is triple board-certified in Internal Medicine, Gastroenterology / Hepatology, and Transplant Hepatology. She attended the University of Pittsburgh School of Medicine followed by internal medicine residency at Emory University, and Gastroenterology and Hepatology fellowship at the University of Colorado. She then completed an advanced fellowship in transplant hepatology at Northwestern University before joining MedStar Georgetown University Hospital.
In addition to patient care, Dr. Nilles has educational and research interests. Her research interests include management and outcomes of acute liver failure and post-transplant rejection, graft, and patient survival outcomes. She has published articles in Clinical Liver Disease, Hepatology Communications, Transplantation, Journal of Hepatology, and other refereed journals and has co-authored book chapters.
When she’s not working, Dr. Nilles enjoys running, skiing, traveling, and reading.
