RESEARCH INTERESTS
Dr. Abushahba’s long-term research goal is to develop novel vaccines and antimicrobials targeting intracellular and antimicrobial-resistant pathogens. During his graduate studies at Purdue University, Dr. Abushahba successfully targeted the rpoA gene in Listeria monocytogenes and methicillin-resistant Staphylococcus aureus (MRSA) using peptide nucleic acids. This innovative work has sparked his interest in genome-wide approaches to understanding gene function—particularly how specific genes influence phenotypes within complex systems such as host-pathogen interactions— and how these insights can drive the discovery of new drug and vaccine targets.
Dr. Abushahba’s ongoing research centers on two main areas. The first investigates the roles of previously uncharacterized genes in the pathogenesis of both human and avian extraintestinal pathogenic Escherichia coli (ExPEC). This work integrates comparative and functional genomics, targeted mutagenesis, in silico prediction tools, and both in vitro and in vivo infection models to functionally characterize these genes. The second project focuses on brucellosis and employs transposon insertion sequencing (Tn-Seq), and mouse models of infection to investigate both how antibodies mediate protection against brucellosis and how Brucella subverts humoral immunity.
