Rabab Ali, M.D.
Post-Doctoral Fellow
Rabab Ali earned her M.D from Ayub Medical College, Abbottabad Pakistan. During her final year in Medical School, she rotated as an elective student in the Liver Disease Branch, NIDDK to gain clinical research experience. This led to her interest in further pursuing a program to apply clinical knowledge to the field of scientific research. She joined the Translational Hepatology Unit, LDB, NIDDK as a Post-Doc Clinical Research Fellow in 2015 and is currently investigating the relationship between the microbiome and the progression of liver disease.

Elizabeth Townsend, B.A.
IRTA Post-Baccalaureate Research Fellow
Elizabeth (Liz) Townsend attended St. Olaf College where she earned her B.A. in Biology and Music Performance. While at St. Olaf College she conducted research on the mechanisms of cellular fat storage. She joined the Translational Hepatology Unit, LDB, NIDDK as a Post-Baccalaureate Researcher in 2015 where she is currently investigating microbial translocation in the context of hepatitis delta associated liver disease.

Mi Sun Moon, Ph.D.
Post-Doctoral Fellow

Mi Sun Moon received her Ph.D. in Microbiology and Immunology from Pennsylvania State College of Medicine, during which time she studied the effect of hepatic iron on acute and chronic liver disease using both in vitro and in vivo models. She then joined the Translational Hepatology Unit, LDB, NIDDK as a post-doctoral fellow in 2012 and currently works on a project investigating microbial translocation in liver disease.

Sandy Page, Ph.D.
Post-Doctoral Fellow

Sandy Page earned a B.A. from the University of Delaware and a Masters in Biology from George Mason University. She worked professionally as an ecologist for state and federal government agencies and for a consulting firm. She then earned a second Masters degree from North Carolina State University, specializing in molecular biology. In 2011 she completed a Ph.D. in Biosciences, with a concentration in Functional Genomics, from George Mason University. Her doctoral research involved the identification and validation of biomarkers of non-alcoholic fatty liver disease. She joined the Translational Hepatology Unit, LDB, NIDDK, in 2012 as a post-doctoral fellow. She is currently investigating whether genetic polymorphisms influence disease progression in patients with hepatitis C.
