She completed her post-doctoral (J-S Hoffmann’s team, CNRS - INSERM U1037) on the mechanisms of control of DNA replication. Anne joined our team in 2015 as Ass. Prof. (Toxicology dpt, Pharmacy faculty of Toulouse) and focused her activities towards the study of replicative stress and host adaptation following exposure to several xenobiotics such as CDT bacterial genotoxin.

Saleha HASHIM, Technician (2011-2020)

  • Saleha was recruited in 2008 and participated to the team creation in 2011. She is technician at the Pharmacy Faculty where she prepares the Toxicology practical courses and participates to the laboratory experiments.

Benoît PONS, PhD student (2016-2019)

  • Benoit studied engineering in biochemistry at the National Institute of Applied Sciences (INSA) in Toulouse. He joined the team in 2016 for his PhD thesis research work, addressing the genotoxic effects of Cytolethal Distending Toxin (CDT) bacterial toxin in colorectal carcinogenesis. Benoît is now a Post-doc in UK.

Vanessa GRAILLOT, Post Doctoral fellow (2015-2017)

  • Vanessa obtained her PhD in Toxicology (University of Toulouse) in 2012 at Toxalim. Her work focused on the quantitative assessment of dietary exposure to mixtures of pesticides and mechanisms of genotoxicity. She was recruited in 2015 to develop a real-time micronucleus assay as part of the Genotrace project.

Bernard SALLES, Prof (2011-2017)

  • Bernard created and headed from 1991 to 2010 the team "Radiobiology and DNA repair" of the IPBS (UMR5089 CNRS / University) dedicated to the repair of DNA lesions and, more recently, DNA breaks. One of the objectives was to validate molecules that sensitize tumor cells to radiation treatment which induce breaks by inhibition of repair activity. The team was supported by various national and regional grants and by the canceropole GSO, the ARC (cancer research association) and La Ligue (League against Cancer labeled team). Bernard leads the new Institute TOXALIM dedicated to the study of food contaminants and their long-term effects on human and animal health.
