Lucile Miquerol, PhD is a research scientist at the Institute of Developmental Biology of Marseille (IBDM) in France. She received her PhD in Human Genetics from Paris 7 University in 1996. After 4 years at the Samuel Lunenfeld Research Institute in Toronto Canada as postdoc, she returned to France at IBDM in Marseille and obtained a CNRS researcher position. During her career, she developed several transgenic mouse models to study diverse biological processes from embryonic development to pathologies such as cancer or cardiac diseases. She received the CNRS Bronze medal in 2005. Since 2000, her project focuses on the development of the ventricular conduction system in mice. The generation of sophisticate genetic tools such as Cx40-GFP or Cx40-CreERT2 mouse lines has allowed her to study the morphology and electrophysiology of cardiac Purkinje fibers and decipher their embryonic origin and to study the development of coronary arteries in embryos or after myocardial infarction.
