Research interests

We use the Drosophila as a model for the study of cardiac function in physiological and pathophysiological contexts.

Our projects are organized around two aspects:

  • Characterizing the autonomic and systemic response of the heart to nutritional stress.

Flies fed high-sugar or high-fat diets develop cardiac dysfunctions similar to diabetic heart disease. A transcriptomic approach allows us to study the genetic basis of the heart's adaptive response to hyperglycemia and excess fat.

  • Determine the natural variations in the genome associated with changes in cardiac function during aging.

Using GWAS-type association genetic analyses on a population of 200 Drosophila inbred lines (DGRP), we have identified genes encoding transcription factors that impact cardiac function during senescence.

External collaborative projects:

Functional validation of orthologs of human genes involved in Brugada syndrome BrS (ANR funding 2022-2027) and in sex dimorphism in the onset of BrS (ANR funding 2026-2030)

Effect of puparium orientation on heart metamorphosis (ANR funding 2026-2029)
