Chef du service de Biostatistique des Hospices de Lyon depuis 2002, le Preneecochardrofesseur René Ecochard enseigne la Biostatistique au CHU de Lyon. Il obtient son diplôme de médecin après avoir soutenu en 1982 une thèse sur la « Régulation des naissances par méthodes d’auto-observation, bases scientifiques et méthodes » à l’université Claude Bernard, Lyon 1.

Il complète sa formation médical  par une Thèse en sciences à l’université de Cambridge (Grande-Bretagne) en 1997, sur les modèles à effet aléatoires d’analyse statistique sur la fécondité (fécondabilité) humaine (« Random Effects Models in the Statistical Analysis of Human Fecundability Data ») dirigée par D.G Clayton, J. Esteve et A. Pickles.

En parallèle de sa formation médicale, le Professeur René Ecochard s’est également formé aux méthodes statistiques, en 1986, et aux Statistiques Appliquées à la recherche clinique en 1987 ainsi qu’aux modélisations des systèmes biologiques. On peut notamment noter l’obtention d’un DEA à l’Université Claude Bernard de Lyon 1 sur « La modélisation d’un phénomène continu sur des données transversales. Les follicules ovariens chez la femme. »

Les sujets prédominants dans les études épidémiologiques réalisés par le Professeur Ecochard sont:

  • Insuffisance Greffe rénale (17 articles)
  • SIDA (21 articles)
  • Hormones du cycle féminin (15 articles)
