Carlos Castillo-Chavez (born March 29, 1952) is a Mexican-American mathematician who was Regents Professor and Joaquín Bustoz Jr.

For 2019, Castillo-Chavez was the Provost Visiting Professor in the Applied Mathematics Division and the Data Science Initiative at Brown University.

In 2006, Arizona State University described him as one of the most prominent mathematicians in the country, an expert in epidemiological modeling, and among the top research contributors to literature on the progression of diseases.

[8] His 52 PhD students included 21 women, 29 from US underrepresented groups and 7 from Latin America, according to a September 2020 update of the public record.

[9] He received recognition for his work on enhancing prospects for academic success and providing research opportunities for underrepresented groups in mathematics and biology.

A graduate student had reported him for creating a hostile environment and harassment, substantiated by an ASU investigation, and the matter was closed without further action upon his retirement.

[13][14] His research program was at the interface of the mathematical and natural and social sciences,[14] with emphasis on: He and his collaborators introduced mathematical models for the spread of scientific concepts, ideas, or media driven information such as, for example, the social contagion effect in recurrent mass killings and school shootings.

[15] They also worked on the role of behavior and mobility on the dynamics of emergent and re-emergent diseases including Ebola, influenza, tuberculosis, and Zika virus.

[24] The Levin Center members have a history of stimulating synergistic cross-disciplinary activities, and initiating biological, environmental and sociological research that involves a significant use of quantitative methods—mathematics, modeling, statistics and simulations.

Research areas include Public Health, Infectious Diseases, Social Dynamics, Human-Environmental Interactions, Theoretical Biology, Applied Mathematics, Statistics and Simulations.

[25] and BS[26] The PhD program at Arizona State University aims to produce "a new generation of scientists with an understanding of global issues and vigorous training in quantitative theory and methods.

[The] graduates come from a wide range of backgrounds and will be able to quickly adapt to the changing employment demands we are already seeing in areas such as homeland security, sustainability and conservation biology, urban system dynamics, public health, disease evolution and addiction, infrastructure and technological research.
