Wassim Abou-Kheir has a broad background in cell biology and cancer research, with specific training and expertise in cancer stem cells in solid tumors. After obtaining his B.Sc. (Lebanese University-Biology) and M.Sc. (American University of Beirut-Biology), he pursued a pre-doctoral fellowship at Albert Einstein College of Medicine (NY, USA). As a Ph.D. student, he carried out research on the signaling pathways that control actin cytoskeleton remodeling and that govern the relationship between tumor cells and the microenvironment, especially tumor-associated macrophages. In 2007, he joined the National Cancer Institute of the National Institutes of Health (NCI/NIH; MD, USA) as a Postdoctoral fellow. His work at the NIH was focused on understanding prostate cancer progression and isolating and characterizing cancer stem cells in a mouse model of prostate cancer. In September of 2011, he joined the Department of Anatomy, Cell Biology, and Physiological Sciences in the Faculty of Medicine at AUB. At AUB, he built a multidisciplinary research group, The WAKers, that focuses on pressing issues in the stem cell field in both normal and abnormal conditions. He is an active member of many international scientific societies, like AACR, ISSCR, and SFN. He is also a member of and ambassador for the EACR.
