About Me My fascination with the liver first began during my medical training, influenced by interdisciplinary hepatology research going on at University of Bern. After completing my medical education, I pursued a PhD in molecular biology and biochemistry working on Wilson's Disease and moved to the US as a postdoc in cancer biology and gene therapy after completing my PhD and internal medicine fellowship. During my education, I have kept the vision of doing interdisciplinary research to improve human health in mind. It is something I have carried over through my time at the Salk Institute and Baylor College of Medicine, where I started my own lab. I am excited to continue pursuing that vision at Duke University and expand therapeutic alternatives to children with inborn error of metabolism.
Outside the lab, I am interested in exploring other countries and cultures, kite surfing and snowboarding or just having a good time with my family and friends
