Jeffrey Lawrence

Jeffrey Lawrence is a Professor and Department Chair at the University of Pittsburgh, specializing in the evolution of bacterial genomes through horizontal gene transfer, ecological adaptation, and genomic architecture. His career spans over two decades, beginning with a Ph.D. in 1991 at Washington University, St. Louis, and postdoctoral work at the University of Utah under John Roth.

  • Ph.D., 1991 (Washington University, St. Louis)
  • Postdoctoral studies, University of Utah

Dr. Lawrence's research integrates computational, theoretical, and experimental approaches to address why bacterial genomes contain specific genes and how evolutionary processes drive species differentiation. He has pioneered studies on fragmented speciation, where genetic isolation occurs gene-by-gene over millions of years, and the role of protozoan predation in Salmonella antigen diversification.

His publications highlight trends in bacterial genome evolution, including constraints on horizontal gene transfer, gene amelioration, and the selfish operon hypothesis. He also contributes to clinical genomics, particularly in prostate cancer biomarkers like the 17-gene genomic prostate score assay.

Dr. Lawrence is involved in educational initiatives such as the Science Education Alliance Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) and advocates for interdisciplinary collaboration in bacterial evolution studies.
