Arturo Casadevall is a microbiologist and immunologist who studies how microbes cause disease and how hosts protect themselves against microbes. His work aims to protect people from harm caused by new pathogens and resistant organisms and by compromised immune systems.

Casadevall has developed novel therapeutic strategies for a variety of human diseases including melanoma and infectious diseases such as tuberculosis. His team is currently focused on understanding how hosts defend against the fungus Cryptococcus neoformans, a ubiquitous environmental microbe that is a frequent cause of disease in people with impaired immunity.

He was quoted in Time Magazine about how climate change could play a role in the spread of coronavirus COVID-19 and other infectious diseases.

He is also well known for his research on scientific misconduct, focusing on fraudulent results published in journals, problems with the funding pipeline, the rise in retractions, and dual use research.
