Dr. Niles is an emeritus professor of microbiology at the State University of New York at Buffalo School of Medicine. He received his Ph.D. in biochemistry from the University of Massachusetts, Amherst. After postdoctoral studies at Yale University, he joined the Biochemistry Department at the SUNY Buffalo. Subsequent to leaving UB, after more than three decades as an academic scientist, Dr. Niles joined BARDA, a division of ASPR in the Department of Health and Human Services. As an Interdisciplinary Scientist, his efforts focused on the development of drugs and vaccines directed against agents of biodefense interest, principally smallpox virus.
Over his career, research in the Niles laboratory ranged from studies on mechanisms of gene transcription and RNA processing in viral and cellular systems to signal transduction pathways in the helminthes parasite Schistosoma mansoni. Principle efforts focused on vaccinia virus transcription and mRNA cap formation. Discovery and development of novel antivirals, antibiotics and vaccines remain topics of keen interest.
