Research Focus 

Dr. Alassiri’s research focuses on leukocyte recruitment in health and disease. The dysregulation of leukocyte trafficking, differentiation and function in chronic disease especially Multiple Sclerosis. He is also fascinated by the differentiation capability of mesenchymal stem cell (MSC) and trying understand factors that control MSC adhesion, homing, and recruitment.  He is the Co-founder of Electrophysiology lab in the King Abdullah International Medical Research Center's (KAIMRC).  Dr. Alassiri is trained on the Xenoplace workstation using Xenopus laevis frogs, and also trained on the two-electrode voltage clamp system.
