Ashraf S. Ibrahim, Ph.D.

Professor of Medicine-in-Residence

Dr. Ibrahim is a Professor of Medicine-in-Residence at David Geffen School of Medicine at UCLA, and a senior researcher and Director of the Graduate Studies Program at the Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center. He conducts basic and translational research in infectious diseases with focus on developing vaccines and immunotherapies as adjunctive therapy to combat priority pathogens with multidrug resistance.
Dr. Ibrahim is an elected fellow of the American Academy of Microbiology (AAM) and European Confederation of Medical Mycology (ECMM) and a recipient of the Billy H. Cooper award for continuous outstanding achievement in clinical mycology. He received PhD in in Microbial Physiology from the from Loughborough University of Technology (UK) and completed his Postdoctoral training in Infectious Diseases at Harbor-UCLA Medical Center.

Dr. Ibrahim currently holds several NIH and industry-sponsored projects and has received over $32 M in funding for his research. He coauthored >200 peer-reviewed research papers, review articles and book chapters. He is a member of the editorial boards of Journal of Fungi and Frontiers in Cellular and Infections Microbiology and a founder of several startup companies that focus on developing innovative protein/nucleic acid-based vaccines, therapeutic antibodies, and rapid diagnostics.
