Audrey is a postdoctoral researcher in the Department of Radiological Sciences at the University of California, Los Angeles. She joined the research group in February 2018. She obtained her PhD in Biostatistics in 2017 from University of Montpellier, France. The aim of her PhD was to optimize the matching between donors and recipients in liver transplantation but also to create a new allocation score based on the Survival Benefit. This latter has been evaluated using Discrete Event Simulations. Currently, she is working on the external validation of various published prediction models in patients at risk of lung cancer and kidney failure.
