Career Aspirations:

Sami's research activities are focused on cancer understanding and treatment. In his MSc and PhD, he associated platinum drugs to high or low radiation in lymphoid and solid cancer to improve treatment efficiency. His first postdoctoral fellowship involved identifying the molecular actors implicated on H2AX phosphorylation and DNA double strand break (DSB) recognition after irradiation. At least 44 kinases that promote a decrease of DSB recognition were identified when one is knocked out.

Currently, he is pursuing an ambitious project aimed at understanding how the metastasis process is regulated in breast cancer; specifically, demonstrating an important role of the Pax-5 gene on the inhibition of EMT and possibly induction of MET. And ultimately, to obtain results that provide a major improvement in the diagnosis and treatment options for breast cancer patients. Sami hopes his experience will lead to a position in an academic institution to initiate his career as a resourceful and independent cancer researcher.
