Pathogenic mechanisms of fungal and bacterial infections
Dr. Ibrahim’s research focuses on advancing the understanding of the pathogenic mechanisms and virulence factors of fungal and bacterial infections, and on translating this knowledge into novel immunotherapeutic strategies to combat infectious diseases. His research is focused on the following areas:
1) The host-pathogen interactions and pathogenesis of mucormycosis and development of rapid diagnostics and novel antibody-based therapy for this fatal fungal infection.
2) Unnatural immunity for the development of vaccine strategies that target multidrug resistant organisms including MDR Candida, MRSA, and Gram-negative bacteria.
3) Mechanisms of microbial sepsis for development of novel immunotherapies.
