Jorge Frias-Lopez, PhD

Jorge Frias-Lopez, Ph.D. is Full Professor in the Department of Oral Biology at the University of Florida College of Dentistry and an internationally recognized leader in microbial ecology, oral microbiology, and host-microbiome interactions. His research has transformed our understanding of how complex microbial communities’ function in health and disease by integrating genomics, systems biology, computational biology, and molecular microbiology. Dr. Frias-Lopez is widely recognized as a pioneer in the application of metatranscriptomics to complex microbial communities. His work introduced innovative approaches that enabled researchers to characterize not only the composition of microbial ecosystems but also their functional activity by measuring gene expression directly within entire microbial communities. These advances have fundamentally changed the way scientists study the human microbiome and have provided powerful tools to investigate microbial behavior, community interactions, and host responses in vivo. His laboratory investigates the molecular mechanisms that govern host-microbiome interactions and microbial dysbiosis, with a particular emphasis on the oral microbiome. Through multidisciplinary approaches combining high-throughput sequencing, computational analyses, microbiology, and immunology, his group has generated landmark discoveries on the functional dynamics of periodontal disease, microbial adaptation during disease progression, CRISPR-mediated regulation of bacterial virulence, and the contribution of the oral microbiome to oral cancer and systemic inflammation. More recently, his research has identified microbial and host transcriptional signatures associated with disease progression and therapeutic response, advancing the development of microbiome-based precision medicine strategies. Before joining the University of Florida in 2016, Dr. Frias-Lopez served as Associate Member of the Staff and Vice Chair of the Department of Microbiology at the Forsyth Institute in Cambridge, Massachusetts, and as Lecturer in Oral Medicine, Infection, and Immunity at the Harvard School of Dental Medicine. He completed postdoctoral training at the University of Illinois Urbana-Champaign, where he studied antibiotic resistance and polymicrobial diseases, and at the Massachusetts Institute of Technology (MIT), where he developed groundbreaking genomic tools that established new standards for functional microbiome research. Dr. Frias-Lopez has authored numerous highly cited publications in leading scientific journals, and his work continues to shape the fields of oral microbiology and microbial ecology by uncovering how microbial communities influence human health and disease. His research aims to translate fundamental discoveries into new diagnostic, preventive, and therapeutic strategies that improve oral and systemic health.

The Frias-Lopez Laboratory investigates how complex microbial communities function and interact with the human host to influence health and disease. By integrating microbial ecology, functional genomics, systems biology, computational biology, and spatial biology, the laboratory seeks to uncover the molecular mechanisms that drive microbial dysbiosis and host-microbiome interactions. A central focus of the laboratory is the functional biology of the oral microbiome. Rather than simply identifying which microorganisms are present, the group aims to determine what microbial communities are doing, how they communicate with one another, and how they interact with host tissues during health and disease. Dr. Frias-Lopez pioneered the application of metatranscriptomics to complex microbial communities, establishing innovative approaches that transformed the study of microbiome function by enabling genome-wide analyses of microbial gene expression directly within natural microbial ecosystems. Current research combines longitudinal clinical studies with multi-omics, spatial biology, and advanced computational approaches to define where microbes are located within tissues, how they interact with neighboring cells, and how these spatial relationships influence disease progression. The laboratory investigates the functional dynamics of periodontal disease, microbial adaptation during disease progression, host and microbial transcriptional responses to therapeutic interventions, CRISPR-mediated regulation of bacterial virulence, and the contribution of the oral microbiome to oral squamous cell carcinoma and chronic inflammation. By integrating functional and spatial analyses of host-microbiome interactions, the Frias-Lopez Laboratory is building a systems-level understanding of microbial communities across space and time. These discoveries are advancing microbiome-based diagnostics and precision therapeutic strategies aimed at preventing and treating oral and systemic diseases.
