Research/Clinical Interest
Clinical Tropical Medicine and Travelers Health; BioSurveillance
1) Development of global provider-based surveillance networks for characterization of infectious disease morbidity in travelers and migrants using innovative electronic communications modalities. Founder of GeoSentinel, a CDC-funded global surveillance network of 50 travel/tropical medicine units on 6 continents. 2) Development of novel techniques for the clinical teaching of tropical medicine to graduate physicians from industrialized countries, on-site in the tropics while maintaining all traditional accreditation standards. Director of the Gorgas Courses in Clinical Tropical in Lima, Peru with 50 participants/years from 12-20 countries. 3) Development of novel strategies to track global trends in disease and occupational health risk among employees of multinational corporations.
