Research Interests

Dr. Nassir’s research interests focuses on understanding the mechanisms involved in the pathogenesis and rescue of non-alcoholic fatty liver disease (NAFLD). In particular, she is interested in the role of mitochondria, sirtuins, inflammation and nutrition as it relates to NAFLD.

Other interests include the regulation of fatty acids uptake as well as the regulation of lipoprotein synthesis and secretion in hepatic and intestinal cells. She uses in vivo as well as in vitro models including primary hepatocytes and enterocytes, and cell lines. Previous research interest includes the role of nutritional status in minerals and oligo-elements in the regulation of hepatic lipid metabolism.
