I have worked as a Professor of Physiology since 2015. My teaching and research career have continued for 3 decades (1989-2023). I earned my PhD in immunology from Brigham Young University (BYU), UTAH, USA and Benha University, EGYPT through channel system (2000). PhD study had focused on monitoring immune elements and DNA damage as a biomarker of aquatic animals in polluted water. I have completed training as a visiting researcher during post-doctoral research work at Games Cook University (Molecular immunology Lab), Townsville, Australia (2014). I had carried out a study on food allergy from seafood. Currently, my research focuses on biosynthesis of collagen and aging in relation to the immune state. Degree(s)
