Dr. Ioulia Tchiguirinskaia is director of the HM&Co Lab and associate professor at the Ecole des Ponts ParisTech, has a PhD in mechanics (UPMC) and an engineer diploma (U. Lomonosov). Her research has been evolving from the analysis of the atmospheric boundary layer, in particular its intermittency, to multi-scale modelling of hydro-meteorological processes, including their extremes. More recently, her research was focussed on the uncertainty reduction of multifractal estimators to widen their use in water management, in particular evaluating the resilience of complex environmental systems. She has co-edited three books and published in international journals of mechanics, hydrology and environmental sciences. She has been an expert with the International Hydrological Programme of UNESCO. She is editor of Nonlinear processes in Geophysics. She has been participating to many European programs and was the ENPC coordinator of the recent FP7-SMARTesT project.
