Professor El-Azizi was appointed as a demonstrator in the department of Microbiology and Immunology, Faculty of Pharmacy, Cairo University from 1988 to 1995, then as teaching assistant in the same department from 1995 to 1997. He worked as research instructor in the division of infectious diseases, School of Medicine, Southern Illinois University, USA from 1997 to 2000. He was appointed as assistant professor in the Faculty of Pharmacy, Cairo University from 2000 to 2002. He worked as associate professor in the Division of Infectious Diseases, School of Medicine, Southern Illinois University, USA from 2002 to 2006. Professor El-Azizi has joined the GUC in 2006 as associate professor then as a professor of Microbiology and Immunology. He was appointed as the Vice Dean for Students Affairs from 2011 to 2019, the Vice Dean for the Faculty of Postgraduate Studies and Scientific research from 2014 to 2019. He is currently the Dean of the Faculty of Pharmacy and Biotechnology and member of the GUC Vice Presidency for Quality. | Research Interests | The major area of his research is medical microbiology, immunology, and infectious diseases including, microbial adherence, biofilms and device related infections, as well as resistance of bacteria and fungi to antimicrobial agents and exploring non-conventional therapy such as nano size antimicrobial agents and immunotherapeutic agents to treat infections caused by multidrug-resistant bacteria. The main goal of the research activity is to come up with real products that can be implemented in the clinical settings to treat infections especially those that are caused by multidrug-resistant bacteria.Professor El-Azizi has 80 publications in peered-review journals and national and international conferences. |
