Sarra Mestiri holds a master's degree in biochemistry and molecular biology from the Sorbonne University of Paris. With over 7 years of research and academic experience spanning Tunisia, France, and Qatar, she has demonstrated expertise in biochemistry and molecular biology. While conducting research in France, Sarra identified novel NF-κB inhibitors through high throughput screening, offering potential regulation for diseases like cancer, auto-immune conditions, and chronic inflammation. Her work also delved into the ATR-CHK1 signaling pathway's role in DNA replication dynamics during replicative stress.

Relocating to Qatar in 2019, Sarra joined the Translational Cancer Research Facility at the National Center for Cancer Care and Research/Hamad Medical Corporation as a Research Associate. Her focus included characterizing immune responses in cancer patients, identifying dynamic biomarkers of response, and generating antigen-specific T cells for cancer therapy. In 2024, she became a Senior Research Associate in Dr. Fares Al-Ejeh's team, dedicating her efforts to identifying clinically actionable potential biomarkers in Qatar's population for Cancer Precision Medicine. With a commitment to advancing cancer research, Sarra Mestiri brings a wealth of experience and expertise to her current role.
