With a university background in ecology and evolutionary biology, my research focuses on studying various aspects of transmissible cancers, including their evolution, ecology and host-cancer interactions.
During my PhD (2018-2021) I studied the biology, ecology and evolution of a transmissible cancer (MtrBTN2) in Mytilus sp. mussels, on the supervision of Nicolas Bierne (ISEM) and Guillaume Charrière (IHPE) at University of Montpellier in France. Using both experimental and empirical approaches, I studied the evolutionary history of this unusual parasite and its interactions with host organisms, particularly the host immune response.
Since October 2022, I joined the TCG team, headed by Pr Elizabeth Murchison, to study the host-cancer interactions of three transmissible cancers affecting mammals: the Canine Transmissible Venereal Tumor (CTVT) in dogs, and the two Devil Facial Tumor (DFT1, DFT2) in Tasmanian devils. Through transcriptomics approached at the single-cell level, I aim to study the tumour microenvironment to better understand how those cancers escape the host immune system and how this could predict the progress and outcome of the disease.
