Dr. George Allen is an Associate Professor and Chair of the Department of Pharmacy Practice at the College of Pharmacy at UNE. Dr. Allen earned his Doctor of Pharmacy degree from the Massachusetts College of Pharmacy and Allied Health Sciences in 1998. Dr. Allen then completed a Pharmacy Practice Residency at the University of Washington in Seattle, WA, and a Fellowship in Infectious Diseases Pharmacotherapy at Wayne State University in Detroit, MI. As a postdoctoral fellow, Dr. Allen performed laboratory-based research examining induction of bacterial resistance by a variety of antimicrobials. Before joining UNE in 2010, Dr. Allen was a member of the faculty at the Oregon State University College of Pharmacy in Portland, OR, where he continued his in vitro research and participated in didactic and experiential education of Doctor of Pharmacy students.

Dr. Allen's research focuses on investigations of the pharmacodynamics of antimicrobial resistance. He uses in vitro modeling techniques that allow evaluation of the effects of varying antimicrobial exposures on the development of resistance. The majority of Dr. Allen's current work consists of studies of two unique measures of antimicrobial activity, the mutant prevention concentration and mutant selection window. This work is performed using a variety of clinically important bacterial species, including Neisseria gonorrhoeae, Klebsiella pneumoniae, Salmonella enterica, and Shigella flexneri, with most research focusing on the fluoroquinolone antimicrobials. Broadly speaking, Dr. Allen's work is designed to determine those antimicrobials (as well as the optimal doses of said antimicrobials) that will best prevent the emergence of bacterial resistance in the laboratory and, potentially, in clinical settings.
