Karine Chalvet-Monfray is a professor of Biostatistics and Epidemiology at VetAgro Sup (Lyon). She is a veterinarian with a PhD and post-doc in biomathematics and statistics. Her research mainly focuses on the modelling of weather-sensitive diseases such as vectorial diseases. Since 2014, Karine has been coordinating the tick network observatories in France (ClimaTick) and in 2009 she participated in the design of FleaTickRisk, a forecasting model that uses meteorological data to predict ectoparasite activity in different climates. In this talk, Karine illustrate the results of 7 years of standardized monthly observations of tick activity and the associated model taking into account various environmental and meteorological factors.
