About me

I am interrested in the study of the relationship between species. This has led me to study crop protection and biological control. Indeed, I believe crop protection to be one of the major leverages to feed the human population in the upcoming century. This study of relationships is even more complex in a changing climate and environment. These challenges, allong with a taste for statistics and computer science have led me to modelling, for instance during my master thesis in Agroclim unit of INRAE.
My curiosity for computer science is originally fuelled by a love for free software but has become more professionnal during my PhD. As a chess player, I was marvelled by the rise of neural networks and deep learning and decided to learn about it around 2016. In 2018, I started a PhD that was at the crossing of all my interests : Ecology, crop protection and deep learning. The goal of my thesis was to identify the predators of the banana weevil using image analysis. My thesis took place in Montpellier and La Réunion island, in France. I was supervised by Philippe Tixier and Dominique Carval in CIRAD in UR GECO for the agro-ecological part of the thesis and William Puech in the ICAR - Image & Interaction team of the LIRMM for the image analysis part. After the completion of my PhD degree in ecology, I was convinced of the potential of image analysis to study ecosystems and continued using image analysis on aerial and satellital images. This is my current occupation at UMR AMAP of CIRAD.
My favorite programming languages are python and R but I can understand and modify C or Rust code. I like to use free software as much as possible (Arch linux, Ubuntu, Neovim, Lichess and Krita are personnal favorites).
I am french but I speak and write German and English fluently. I have travelled a lot in Germany during highschool and studies. I may have lived around a year of my life in Baden-Württenberg. I speak a little spanish and I am currently learning a bit of french sign language.
In my free time, I like to paint, read, ride my bicycle, hike, tinker with old computers and occasionnaly spin on my head or knitt a little !
