Dr. Nagwa Ibrahim Saad Abu-Zahra is a dedicated researcher at the Animal Health Research Institute (AHRI), part of the Agriculture Research Center in Giza, Egypt. Her research focuses on aquatic animal health, particularly the physiological, immunological, and toxicological responses of Oreochromis niloticus (Nile tilapia) to environmental stressors and dietary interventions. She has authored several peer-reviewed publications in respected international journals such as Scientific Reports, Aquaculture International, and Veterinary Research Communications. Her work explores the protective effects of natural compounds like spirulina, curcumin, and peppermint against pollutants and pathogens, contributing to safer and more sustainable aquaculture practices. Dr. Abu-Zahra’s research has been cited in the global scientific community, reflecting growing recognition, and she maintains an H-index of 3 with multiple recent publications. Beyond her authorship, she actively contributes to scholarly peer review, having completed 21 verified reviews for reputable journals. Her interdisciplinary approach integrates aspects of toxicology, immunology, and fish physiology, making her work relevant to biophotonics, particularly in assessing oxidative stress and cellular changes using biological markers. Through collaboration and scientific service, Dr. Abu-Zahra continues to impact the field of aquatic veterinary science and is well-positioned for future advancements in research and academic leadership.
