Jeffrey Scott McLean , PhD

Associate Professor, Periodontics

Office D-586, Lab D-558


Dr. McLean received his PhD at the University of Southern California and his MSc at the University of Guelph in Canada. Dr. McLean’s research career at the Pacific Northwest National Laboratory, the J. Craig Venter Institute and now at the University of Washington School of Dentistry has been primarily devoted to developing innovative methodologies, tools and new genomic based approaches to study microbial interactions within oral biofilm communities. Currently, he is funded as a PI on multiple active NIH R01 grants that employ generation sequencing techniques such as single cell genomics and metatranscriptomics to characterize the microbial processes that lead to dental caries and maintain the health of the human oral microbiome. Within these projects, one goal is to isolate and capture genomes of oral pathogens and uncultivated novel oral phlya to gain a better understanding of these polymicrobial diseases and pathogen transmission routes.
