Since 2008, Renaud Piarroux has been a professor at the University of Aix-Marseille and head of the Parasitology and Mycology Service at the Public Hospital of Marseille. He is a pediatrician specialized in infectious diseases and tropical medicine. He set up the Parasitology and Mycology Service of the University Hospital of Besançon and managed it from 1996 to 2008.
Renaud Piarroux has taken part in several missions and research studies in Africa, including the study of the dynamics of cholera epidemics in the Comoros, the Democratic Republic of Congo and West Africa, the prevention and management of parasitic diseases in Morocco, and the implementation and coordination of a program to combat water-related diseases in Côte d’Ivoire. He has taken a special interest in analyzing risks of epidemics and defining health priorities after natural disasters or in the event of conflict (conflict in Afghanistan and in the former Yugoslavia, cyclone in Honduras, volcanic eruption in the Democratic Republic of Congo…). More recently, at the request of the Haitian authorities, he conducted an investigation on the origin of the cholera epidemic in this country since October 2010 and identified that it started in a military camp. Since 2012, he has regularly been carrying out epidemiological studies on the course of the cholera epidemic in Haiti in order to guide the anti-cholera activities conducted by UNICEF and its partners in the field.
He has contributed to the research of the French Society of Parasitology (SFP) and of the French Society of Medical Mycology (SFMM). He was regional delegate for Franche-Comté for the association Médecins du Monde and was in charge of various missions in Grande Comore and the Democratic Republic of Congo.
