Postdoctoral Researcher in Genome Stability
Mutations in BRCA1 and BRCA2 are found in familial and sporadic cancers. BRCA1/2 play key role in DNA damage response (DDR) by promoting homologous recombination (HR) and protecting stalled replication forks. My research projects aim to identify causes of DNA damage in cells lacking BRCA1/2 and to understand their consequences. Indeed, S phase DNA damage can be carried over and transmitted to daughter cells. As an example, we recently showed that BRCA2 loss causes micronuclei formation and activates a type I immune response (Reisländer et al., 2019). A current aspect of my research is to understand how BRCA2 protects from mitotic DNA breaks, and thus prevents micronuclei formation in healthy tissues. Ultimately, this would bring a better understanding of the role of BRCA1/2 and inform on new biomarkers or treatment strategies.

After completing high school in France, I studied biology at the university of Basel (Switzerland) and obtain a BSc degree in 2016. Next, I pursued my master thesis within Sebastian Hiller's laboratory. There, I used Nuclear Magnetic Resonance (NMR) and other biophysical techniques to characterize chaperone-client interactions, and graduated with a MSc in 2018. Before leaving Basel, I joined Radek Skoda's team and contributed in the understanding of mechanisms underlying familial erythrocytosis (Zmajkovic et al., 2018). In spring 2018, I started my DPhil journey as a Marie-Curie student in Madalena Tarsounas' research group.
