I am  infectious disease and run a clinical and research laboratory that performs molecular identification, fingerprinting, susceptibility testing of nontuberculous mycobacteria which I have done for more than 30 years. I have published more than 350 papers, most of which deal with clinical and laboratory characteristics of nontuberculous mycobacterial species. I am a fellow of IDSA, the American College of Physicians, the American College of Chest Physicians, and the American Academy of Microbiology.  My clinical and laboratory interests are susceptibility testing of current and new antimicrobial agents, molecular mechanisms of drug resistance, molecular fingerprinting of mycobacterial outbreaks, defining new pathogenic species, and  exploring the role of genomic sequencing with these organisms.
