Dr. Luethy is an Assistant Professor at the University of Maryland School of Medicine, Department of Pathology. He is also the Assistant Director of the Clinical Microbiology and Virology Laboratories at the University of Maryland Medical Center. He completed a CPEP-accredited fellowship in Medical and Public Health Laboratory Microbiology at the National Institutes of Health Clinical Center and is a Diplomate of the American Board of Medical Microbiology with expertise in the diagnosis of infectious disease.
Dr. Luethy's research interests include evaluating current and novel infectious disease diagnostics for their utility in the clinical laboratory and for improving patient care. He also is interested in developing molecular tools, including Next Generation Sequencing (NGS), for use in the clinical laboratory as well as for investigating research questions such as how microbiomes change following the treatment of infectious diseases.
