Navarro’s research focuses on the complexity of the host-associated and environmental microbiome, including viruses, bacteria, archaea, fungi, and protists. In his research, Navarro studies the composition of microbial communities, their dynamics in a changing environment, and how microbial activity influences nutrient cycling. The complexity of such studies requires the use of chemical analyses, traditional microbiology tools for the isolation of microbes, and, most importantly, molecular tools such as metabarcoding, metagenomics, and metatranscriptomics. Processing and interpreting the vast amount of data generated by this multi-faceted research requires the use of diverse bioinformatic approaches to identify the associations between environment, microbial associations, and ecosystem functioning.

His teaching goal is to inspire students to become explorers of nature’s complexity, use critical thinking and master the use of tools of traditional and molecular biology. Besides his scientific and pedagogical work, Navarro is committed to reducing the barriers in research for underrepresented students, including people of color, women, and LGBTQ+ individuals.
