Laetitia is a molecular biologist using the model organism C. elegans, a microscopic nematode to answer fundamental questions. Her work focuses on stress response, which is a highly conserved protective response, induced under stress in order to maintain protein homeostasis by preventing protein misfolding and aggregation. The stress response is key to protect against neurodegenerative diseases, during ageing, and is hijacked by cancer cells. Laetitia’s work focuses on understanding inter-individual variability in stress response gene expression and its consequences on physiology. C. elegans is a great model to address this question, as these worms are genetically identical and their transparency allows the use of fluorescent gene expression reporters in different tissues.

Laetitia is a postdoctoral researcher in the Epigenetics Department at the Babraham Institute.
