About Us

ExcaliVir, a molecular diagnostics company, was formed in 2012 by Dr. Erle Robertson and Dr. James Alwine, researchers from the University of Pennsylvania, Perelman School of Medicine to transform pathogen detection by combining next generation microarray and sequencing. Their passion for research on the relationship between the microbiome and human cancer has led to the development of a unique technology for rapid identification of all known infectious agents associated with human disease.
