Ping Xu

Ping Xu is a Professor in the Department of Oral and Craniofacial Molecular Biology at Virginia Commonwealth University School of Dentistry. With a Ph.D. in Molecular Biology from Oxford University and Nanjing University, Dr. Xu has established himself as a leading researcher in microbial genomics and oral microbiology. His work bridges the gap between basic molecular biology and clinical applications in dentistry and infectious diseases.

• B.S. in Biology, Nanjing University, 1982

Dr. Xu's research primarily focuses on the human microbiome and microbial genomic research using next-generation DNA sequencing technology and bioinformatics. His laboratory also investigates biofilm and microbial interaction studies using systems biology approaches. His extensive publication record spans over two decades, demonstrating consistent contributions to understanding bacterial pathogenesis, particularly with Streptococcus species and other oral pathogens. His work has significant implications for understanding infectious endocarditis, periodontal disease, and developing novel antimicrobial strategies.

Analysis of Dr. Xu's recent publications reveals a strong emphasis on molecular mechanisms of bacterial virulence, particularly in Streptococcus sanguinis, with applications to oral health and systemic diseases. His research integrates genomics, transcriptomics, and systems biology approaches to understand microbial interactions in complex communities. The interdisciplinary nature of his work connects dental research with broader microbiological and medical fields.

Dr. Xu has contributed significantly to the development of genomic resources for bacterial pathogens, including the creation of ePath, an online database for essential gene annotation in prokaryotes. His work on bacterial fitness genes in human serum has potential implications for developing targeted antimicrobial therapies that specifically disrupt pathogen survival in the bloodstream without affecting commensal bacteria.

His research group has made important contributions to understanding how oral bacteria interact in polymicrobial communities, particularly how hydrogen peroxide production by commensal streptococci affects periodontal pathogens. This work has implications for developing microbiome-based therapeutic approaches for periodontal diseases.
