PhD Student · Deep Learning, Ecology & Remote Sensing · UMR LETG, CNRS / Université Rennes 2
I am a PhD student at UMR LETG (CNRS / Université Rennes 2), working at the intersection of computer science, remote sensing, and ecology. My research focuses on training deep Species Distribution Models (SDMs) to map the spatial distribution of three groups of emerging aquatic insects (Ephemeroptera, Plecoptera, and Trichoptera).
These insects provide critical ecosystem services, including organic nutrient transfer, pollination, and crop pest control. To build high-resolution habitat maps, I use drone-based data (multispectral imagery and LiDAR-derived digital elevation models) and combine them with deep learning methods. A particular focus of my work is on explainability (XAI): understanding why models predict where they do, in order to make AI-driven ecology more interpretable and trustworthy.
I am supervised by Thomas Corpetti and Thomas Houet. My PhD started in April 2024 and is expected to conclude in June 2027.
Deep Species Distribution Models
I develop and train deep Species Distribution Models (SDMs) to predict the spatial distribution of three orders of emerging aquatic insects: Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies). The emergence of these insects contributes to the provision of essential ecosystem services such as nutrient cycling, pollination, and pest control.
My models integrate very high-resolution drone imagery and LiDAR data to capture fine-grained landscape features that drive insect presence.
Drone Remote Sensing
A key component of my work is to explore the value of very high-resolution drone data (multispectral and LiDAR) for the development of fine-scale SDMs. This raises key questions, such as the influence of the choice of sensor, grain size, and spatial extent on DeepSDM model's predictions. Consequently, I also use satellite, super-resolution and government data for comparison purposes.
Explainable AI (XAI)
Making deep learning models interpretable is central to my research. I work on concept-based explainability methods applied to SDMs, with the goal of identifying which landscape features (concepts) drive model predictions. This contributes both to ecological understanding and to building trust in AI-assisted biodiversity assessment.
I have released a high-resolution landscape dataset designed for concept-based XAI benchmarking — see the Publications section for details.
