Biography —

Caetano holds a B.Sc. (2000) and M.Sc. (2002) in Microbiology from Universidade Federal do Rio de Janeiro (Rio de Janeiro, Brazil). He completed his Ph.D. at the University of Iowa (2003-2007) and then moved to Canada for his post-doctoral studies (2008-2012) at the University of British Columbia. In 2012, Caetano was a Researcher in Public Health at Fundação Oswaldo Cruz, in Rio de Janeiro, Brazil. Caetano and his group transitioned to KU in January 2023.

Education —

Ph.D., University of Iowa, 2007, Iowa City, Iowa
M.S. in Microbiology, Universidade Federal do Rio de Janeiro, 2002

Research —

Caetano´s research group is interested in the role of small molecules in host-microbe interactions. In particular, they study the impact of microbiome-derived small molecules on bacterial pathogen gene expression and behavior. Caetano and his group have shown that the human gut is teeming with small molecules, and that the gut metabolome controls expression of various virulence attributes in enteric pathogens.
