Hassan Lemjabbar-Alaoui, Ph.D. is a biomedical scientist and Principal Investigator in the Thoracic Oncology Laboratory. Dr. Alaoui received his Ph.D. from the University of Paris XII.  Since receiving his Ph.D. from the University of Paris XII, he has been studying the epidermal growth factor receptor (EGFR), the reactivation of embryonic signaling pathways, and the roles these play in lung carcinogenesis.  Dr. Alaoui began these studies in 1997 as a postdoctoral fellow/Assistant Research Anatomist in Dr. Carol Basbaum's lab at UCSF, continued them as an Associate Research Anatomist in Steven Rosen's lab, and then as an Assistant Professor of Anatomy at UCSF. 

Dr. Alaoui's research is focused the role of the epidermal growth factor receptor (EGFR) in lung carcinogenesis as well as reactivation of embryonic signaling pathways such as Wnt signaling.The Alaoui Lab is a core component of the UCSF Thoracic Oncology Lab, Dr. Alaoui is currently investigating two extracellular regulators of Wnt signaling, Sulf-1 and Sulf-2, as new therapeutic targets and their role in promoting cell proliferation, survival, and angiogenesis, and in resistance to chemotherapy. Characterized a decade ago in the lab of Dr. Steven Rosen, these enzymes act on extracellular heparan sulfate. Sulfs remove specific internal sulfate residues from heparan sulfate proteoglycans (HSPGs) on both the cell surface and within the extracellular matrix.
