Title of the thesis

Transgenerational effects of CMIT/MIT on a keystone species in freshwater ecosystems.
Supervisors: Scott McCairns and Marie-Agnès Coutellec

Current research topics

The general objective of my thesis is to identify the potential impacts of the biocidal mixture CMIT/MIT and Methylisothiazolinone on the freshwater aquatic environment. These preservatives are widely used in cosmetics and cleaning products and are reported as a danger to the aquatic ecosystems, but their long-term consequences on the environment are not well documented. The model species Daphnia pulex is used to study the toxicity of the biocide on different lines of clonal individuals over four generations. My work focuses more specifically on the effects at the transcriptional and epigenetic levels of direct and transgenerational exposure to MIT.
