Biography

Dr. Werth received his PharmD from the University of New Mexico before completing a pharmacy practice residency at The Queen’s Medical Center in Honolulu, HI. He then completed an Infectious Diseases Pharmacotherapy Fellowship at Wayne State University in Detroit, MI before joining the University of Washington Department of Pharmacy as an Assistant Professor in 2013.

Dr. Werth’s research interest is in antimicrobial resistance and the pharmacokinetics and pharmacodynamics of antimicrobials. His interdisciplinary translational research program is primarily focused on understanding the mechanisms of cross-resistance among glycopeptides, lipopeptides, and lipoglycopeptides in Methicillin-Resistant Staphylococcus aureus (MRSA).
