I have a particular interest in the mathematical formalization of concepts such as resilience and sustainable development.
I am a researcher interested in Probability Theory applied to Ecology and Evolution. I joined IRSTEA in 2015. During the year 2015, I was an academic visiting the Department of Statistics at the University of Oxford. I defended my PhD thesis in the beginning of 2015. My supervisors were Sylvie Méléard (Ecole Polytechnique) and Jean-François Delmas (Ecole des Ponts et Chaussées). I am an Ingénieur des Ponts, des Eaux et de Forêts, and a former undergraduate student of the Ecole Polytechnique.
I am a PhD student at IRSTEA. I work on modeling the spatial dynamics of an invasive clonal plant: the Japanese knotweed. The goal is to find optimal management techniques. The model is written in terms of measure valued stochastic process, solution of a stochastic differential equation. I study the model with mathematical tools (limit in large population) and simulations (I use OpenMOLE software).
My current research activity is related to the integration of the large multi-source and multi-scale brain data. This work concerns the multimodal MRI image processing, its integration with experimental data in genetics and the large bibliographic metadata databases. This work inferred a new model that integrates different types of images in a functional model of information processing by the brain, as well as to a platform “linkrbrain.org” which allows researchers and clinicians to easily connect different types of images and extract new relation graphs.
MACA is a research programme on Autistic cognition, with optimal cognition as its conceptual tool. Its main objectives are to map general cognitive and perceptive abilities of autistic individuals and to propose a taxonomy of autism that would integrate peaks of intellectual abilities. MACA is developed around three major research axes: (i) video games, (ii) Asperger Syndrome for women (iii) the uses of the OMNI (http://musaiques-asso.com/
Key words: Experimental Psychology, Gamification, Cognition, Autism
Computer science researcher working on Politoscope. I study the structure of networks such as the Twitter network for the Politoscope project. The main objective is to detect communities of political activists on Twitter but also, and above all, to track their evolution through time. This allows citizens and journalists to better understand the political organization existing on Twitter. To this end, I use and create graph analysis tools.
Key words: Graph, Community Detection, Temporal Network.
After 6 years in Communications, I decided to stop talking about tech and start being a part of it. This internship is the final step of my training as Junior Web Developper. My mission is to help developing web and mobile applications showcasing researchers’ works.
