Research: Liver physiology, pathology and molecular signatures. Non-alcoholic fatty liver disease (NAFLD) is now the leading cause of liver disease in North America and can lead to Type II diabetes, liver cirrhosis (requiring liver transplantation), liver cancer (hepatocellular cancer, ) and increase the probability of other types of cancer spreading to the liver (liver metastasis). With the help of our human tissue bank and technologies such as proteomics and genomics, we hope to find new therapies for these diseases

Expertise: liver metastasis; liver ischemia/reperfusion injury; non-alcoholic liver disease; hepatocellullar carcinoma; neuroendocrine tumors; proteomics; tissue banking
