ExpoXai

Role: PhD main supervisor
Dates: 2020 - 2023
Funding: PhD student saraly + support
Source of funding: ANRT CIFRE
Collaborators: Meersens - ISGlobal (Barcelona)
This project aims at using Explainable AI to better understand the role of exposome on human health. The exposome describes the set of all factors to which inidivuals are exposed. Understanding which factor has an effect on which person is a major challenge given the quantity and variety of factors. We propose in this project to use state-of-the-art machine learning techniques, and to use Explainable AI (XAI) to provide explanations on the risks to which individuals are confronted to.

ANR serious

Role: Partner, intern co-supervision
Dates: 2022 - 2025
Source of funding: ANR
Collaborators: Ecologie Microbienne Laboratory
The goal of this project is to study the relation between mosquito and urban environment, in particular in the context of fighting Mosquito-driven viruses. Our contribution consist in the anlysis of correlation networks between different factors impacting mosquito development.

Understanding Network Organization

Role: -
Dates: 2010 - ...
Funding: None / Many
Source of funding: None
I'm interested in the organization of networks: communities, spatial structure, and any other type of organization. I work on this question when I'm not busy on another project.

Source of funding: EC2CO
Collaborators: Microbial Ecology lab, Lyon
The goal of this project is to study the mosquito holobiont, in particular in the context of fighting Mosquito-driven viruses. Our contribution consist in the anlysis of correlation networks inside the holobiont.

Sequential Graph Neural Networks for traffic prediction

Role: Project Member, Internship supervision
Dates: 2019 - 2020
Source of funding: IMU
Funding: 3k€ (co-supervised Internship)
Collaborators: Angelo Furno
The goal of this exploratory project is to initiate a collaboration between reserachers in Machine learning and in the traffic domain in Lyon, in particular on the usage of Graph Neural Networks for traffic prediction.

Automated Discovery of the Organisation of Complex Systems

Role: Project Leader, PhD main supervisor
Dates: 2017 - 2021
Funding: 8.5k€ + 1 PhD Student (env. 100k€)
Source of funding:
Lyon 1 University (BQR)
CDSN (PhD student)
Collaborators: Claire Lesieur (Laboratoire Ampere, ENS de Lyon, Lyon, France)
Complex Systems are systems composed of multiple parts in interaction that cannot be understood by reductionnism. Interactions/Relations between parts of these systems can be represented by complex networks. Several models of networks organisation exist: Communities, Core/Periphery, Low dimensional embedding, etc. In this project, we will explore how one can automatically discover the best model for a given network without a priori structure, using variants of Occam Razor's principle.

Studying properties of networks Embedding

Dates: 2018
Role: Project Leader, Master Internship Co-supervision
Funding: 3.5k€
Source of funding: Federation Informatique de Lyon
Collaborators: Christine Largeron (Laboratoire Hubert Curien, St Etienne, France)
Graph embedding, or network embedding, is a potential game changer in network analysis. In this exploratory project, we will catch up with state of the arts tools and techniques for network embedding, and propose an embedding preserving the dynamic of networks. We will particularly focus on highly dynamic networks composed of link streams, or instantaneous interactions.

Role: Project Member
Source of funding: FUI
Collaborators: THALES, PAYMIUM
The goal of this project was to use data mining and graph analysis techniques to help discover suspicious activities in the bitcoin transaction network.
