Teaching Experience:
Undergraduate Teaching: I teach medical microbiology courses within the System-Based Integrated Curriculum for second, third, and fourth-year medical and surgical students. These courses cover the musculoskeletal, nervous, genitourinary, and circulatory systems. I also teach medical bacteriology, medical virology, and diagnostic microbiology courses to undergraduate students in the Medical Laboratory Sciences program at the Faculty of Medicine and Health Sciences.
Postgraduate Teaching: I have taught microbiology and immunology courses to master’s students at the Faculty of Dentistry. Additionally, I taught a microbiology course as part of the USMLE Step 1 preparatory program for graduates of the medical and surgery program.
Academic Supervision: I supervised dozens of graduation research projects for undergraduate medical laboratory students, guiding students from selecting research titles and preparing research proposals to discussing results. This allowed me to gain extensive knowledge of the epidemiology of infectious diseases in my country and experience in guiding research addressing the health situation in Yemen.

Scientific & Research Experience:
My main research interest is the surveillance and characterization of infectious disease threats in Yemen. I employ a comprehensive research approach, starting with the molecular identification of pathogens and their resistance mechanisms, connecting this to clinical disease in vulnerable populations, and extending my research to the public health behaviors that determine the success of preventive measures. My research activities aim to provide accurate scientific data that contribute to the improvement of public health policies, clinical practices, and infection control in a resource-constrained setting such as Yemen.
My main research interests include:
Antimicrobial Resistance (AMR) and its Molecular Mechanisms: I investigate the prevalence, patterns, and underlying genetic causes of drug resistance in clinically significant bacteria.
Epidemiology of Infections in Vulnerable Populations: A significant portion of my research is dedicated to studying pathogens that pose a high risk to specific, vulnerable patient groups. This work is crucial for developing targeted prevention and control strategies.
Public Health, Vaccine Acceptability, and Healthcare System Challenges: My research extends from the laboratory to the community, addressing critical public health issues and the human factors that influence health outcomes.
Funded research projects:
I have successfully secured funding for several competitive and important research projects as a principal investigator and co-investigator through the WHO’s Joint EMRO/TDR Executive Research Grant. These projects addressed critical topics such as the devastating costs of tuberculosis, COVID-19 vaccine acceptance among healthcare workers, neonatal sepsis, and community pharmacists’ knowledge and practice regarding malaria.
I am also currently supervising two doctoral dissertations that deal with the molecular characteristics of beta-lactam antibiotic resistance mechanisms in a number of Gram-negative bacterial species isolated from clinical specimens.
