I have been worked the last 22 years in the Antimicrobial Resistance Division of the National Institute of Infectious Diseases-ANLIS “Dr. Carlos G. Malbran”, “National Reference Laboratory for Antimicrobial Resistance” for the Ministry of Health and “Regional Reference Laboratory for Antimicrobial Resistance” for PAHO/OMS. I work in Surveillance Programs including S. pneumoniae, N. meningitidis and H. influenza of PAHO SIREVA II. I coordinate the "Latin American Program for Quality Control in Bacteriology and Antibiotic Resistance" and the "Caribbean External Quality Assurance Program in Bacteriology and Antimicrobial Resistance" supported by the PAHO including 27 National Reference Laboratories from 27 countries. I have been working on molecular characterization of antimicrobial resistance mechanisms and molecular epidemiology of multidrug-resistant Gram-positive bacterial pathogens. I have published more than 40 papers in international journals.
