My lab studies how the different cell types in the liver, in particular the hepatocyte, are generated during development, patterned and maintained during adulthood, and regenerate after injury. Our long-term goals are to improve the understanding of liver disease pathophysiology and develop novel methods of treatment for liver diseases, including cell replacement therapy. Currently, we have two major research focuses: 1) understanding the biology of adult hepatocyte stem cells and 2) developing a liver cell atlas. We take innovative and integrated approaches to address these two areas using the tools of stem cell biology, developmental biology, genomics and tissue engineering.
I also study the porphyrias, a group of inherited diseases related to defects in heme synthesis pathway. I am a member of the Porphyrias Consortium, a NIH sponsored Rare Disease Clinical Research Consortium. The purpose of the network is to integrate translational studies of the porphyrias with clinical trials testing new therapeutics.
