Dr El-Sabban did his post-doc  studies at the Nuffield Department of Clinical Biochemistry, Radcliffe Infirmary, Oxford University (1985). His Postdoctoral training included Department of Pharmacology, Cornell University, Ithaca NY (1989) where he continued as a Research Associate in the Cancer Biology program. He was then a Research Associate in the Department of Neuroscience at Albert Einstein College of Medicine, NY, USA (1995) and then an Assistant professor of Medicine at SUNY Stony brook and then the Director of Cell Biology Laboratories at Winthrop-University Hospital, NY, USA (1997). His research interests involve the role of cell-cell and cell-matrix interaction in cellular function with special focus on organ-specificity of cancer metastasis. Interaction between host tissues and cancer cells: Molecular mechanisms of cancer cell extravasation, invasion and metastasis; Hetero-cellular interactions and niche function in cancer development. Also, organ-specific stem cell differentiation: novel approaches to Regenerative Medicine and drug screening.
