Education:

Ph.D., 1996, Montana State University

Dr. DeLeo received his Ph.D. in microbiology from Montana State University in 1996, studying the molecular basis of superoxide generation by human neutrophils. He did his postdoctoral training in the area of innate immunity and infectious diseases in the Department of Medicine at the University of Iowa (1996–2000). Dr. DeLeo joined the staff at the NIAID Rocky Mountain Laboratories in 2000 as a tenure-track investigator. He served previously as Acting Chief (2007-2013) and Chief (2013-2015) of the Laboratory of Human Bacterial Pathogenesis. Dr. DeLeo was appointed to the NIH Senior Biomedical Research Service (2011-2017) and elected as an American Academy of Microbiology Fellow in 2017. He is currently Chief of the Laboratory of Bacteriology.

During her doctoral training under the mentorship of Dr. Tabernero, Paulina’s research was focused on characterizing virulence factors for the development of non-antibiotic drugs for tuberculosis. Paulina’s research interest in Dr. DeLeo's lab is to identify bacterial drug/diagnostic targets by studying their evasion of the innate immunity.
