Chaz Langelier, MD, PhD

Associate Medical Director
Medicine

The translational research in my lab bridges basic and clinical investigation by engaging genomic technologies to understand relationships between microbes, host response and clinical outcomes. We study lower respiratory tract infections, ARDS, sepsis, nosocomial infections, and emerging pathogens including SARS-CoV-2. One focus area involves developing new diagnostic techniques that combine metagenomic sequencing and machine learning to simultaneously profile both host and microbiome from clinical samples.
