Jacques Fellay is a medical doctor and researcher, with expertise in genomics and infectious diseases and strong interest in personalized health. He is the founding director of the Precision Medicine Unit of the Lausanne University Hospital (CHUV) and leads a genomics laboratory at the EPFL School of Life Sciences. The aim of his research is to decipher the genetic basis of inter-individual differences in immunity and responses to infections. His group explores the role of human genetic variation in the host-pathogen battle, in the hope of shedding new light on basic biological mechanisms, and of paving the way toward more personalized approaches to health. He received multiple awards, including the National Latsis Prize in 2011 for his work on the genetic control of HIV and hepatitis C virus infections.
