Khalid Al-Nedawi, PhD

Assistant Professor
Department of Medicine
McMaster University and St. Joseph’s Healthcare
50 Charlton Street East
Hamilton, Ontario, Canada


Dr. Al-Nedawi received his PhD in Medical Biology and Biotechnology. He received a post-doctoral fellowship and scientific adjunct position at the center for medical research at the Polish Academy of Science. He joined McGill University as a post-doctoral fellow and later as medical scientist and faculty lecturer. Dr. Al-Nedawi has received several awards and recognition for his scientific accomplishments. He is the winner of the 2010 Michael G. DeGroote academic fellowship award at McMaster University. Currently, Dr Al-Nedawi is an Assistant Professor at McMaster University/Department of Medicine.


Dr. Al-Nedawi has contributed to research on thrombosis haemostasis, cancer progression, angiogenesis, metastasis and biomarkers. Dr. Al-Nedawi’s primary interest is the mechanisms of intercellular interactions through short exosomes / microvesicles. Dr. Al-Nedawi reported the mechanism by which cancer cells can shed oncogenic proteins via microvesicles to the neighboring non-cancer cells providing them with an ectopic transformed phenotype. Furthermore, he reported the transfer of oncogenic proteins from cancer cells to tumour endothelial cells triggering the angiogenic switch. In addition, he contributed to the detection of oncogenic proteins in the cargo of microvesicles circulating in the cancer patient’s peripheral blood. Dr. Al-Nedawi has published in high ranked medical journals like “Blood, ATVB, NCB, PNAS”, and contributed to many international scientific conferences. Dr Al-Nedawi is funded by prostate cancer Canada (Movember foundation), and St Joseph’s Hospital. Dr Al-Nedawi lab located at St Joseph’s healthcare, Hamilton Center for Kidney Research. A postdoctoral fellow and four graduate students, currently working in Dr Al-Nedawi’s lab pursuing different research projects.

Research Interest

His research interests include: Microvesicles/exosomes as source of biomarkers, Intercellular communication through microvesicles and short peptides, Signal Transduction, Biology of Cancer and cellular transformation, Angiogenesis, Transgenic mouse and stem Cell biology, Thrombosis – Haemostasis
