Researchers from NC State University and the University of São Paulo have developed a risk-based priority index to help reduce leptospirosis in Brazil.
Gustavo Machado is an epidemiologist specializing in emerging and transboundary infectious diseases.
Originally from Brazil, he has ongoing collaborations in his home country, and through his postdoctoral position in the Veterinary Population Medicine Department at the University of Minnesota, he has built collaborations with researchers in Kazakhstan and Russia.
At NC State’s College of Veterinary Medicine, where he currently holds a position as Assistant Professor in the Department of Population Health and Pathobiology, Machado uses computer modeling to predict the risk of emerging infectious diseases around the world, using data collected from countries with past or present disease endemics. With these models, he develops methods for preventing disease emergence in unaffected countries, and ways to control the spread of existing outbreaks.
Since his PhD degree at the Federal University of Rio Grande do Sul in Porto Alegre, Brazil, Machado has used several approaches for risk prediction and the establishment of automatic classifications, including machine learning, spatial and temporal mapping, and population genetics. He focuses his research on the dynamic properties of infectious diseases in the geographic space, and uses remote sensing data and environmental factors associated with disease occurrence and transmission to predict disease spread and occurrence.
