Dr. Yang is an Associate Professor in the Department of Emergency and holds a joint appointment in the Institute of NanoBioTechnology. Upon completing both his residency and research fellowship in Emergency Medicine at Johns Hopkins. Dr. Yang joined the faculty in 2005. As a front-line emergency medicine physician with background in molecular & cell biology and clinical investigation, Dr. Yang's research interests have focused on the development and validation of molecular-based point-of-care diagnostics for broad-scale pathogen detection. Specific clinical applications include sepsis, meningitis, septic arthritis, sexually transmitted diseases, HIV, influenza, and bioterrorism. Dr. Yang also collaborates with JHU Whiting School of Engineering to advance microfluidic technologies into practical diagnostic platforms with enhanced performance and capabilities for use in resource-limited settings. Dr. Yang holds several patents and awards for his ongoing research endeavors supported by NIH, NSF, DHS, and other private funding agencies.
