John Glass, PhD

Director, La Jolla Campus
Professor

John Glass is a professor, leader of the JCVI Synthetic Biology Group, and La Jolla, CA Campus Director at the J. Craig Venter Institute. His expertise is in molecular biology, microbial pathogenesis, RNA virology, and microbial genomics. Dr. Glass is also an adjunct faculty member of the University of Maryland at College Park Cellular and Molecular Biology Program, and member of the Global Viral Network Scientific Leadership Board.

Dr. Glass is part of the Venter Institute team that created a synthetic bacterial cell. In reaching this milestone, the Venter Institute scientists developed the fundamental techniques of the new field of synthetic genomics including genome transplantation and genome assembly. Dr. Glass was also leader of the JCVI project that rapidly made synthetic influenza virus vaccine strains in collaboration with Novartis Vaccines and Diagnostics, Inc., and Synthetic Genomics, Inc. At the JCVI he has also led the bacterial outer membrane vesicle based vaccine, genome transplantation, and Mycoplasma genitalium minimal genome projects, and projects studying other mycoplasma and ureaplasma species. Glass and his Venter Institute colleagues are now using synthetic biology and synthetic genomics approaches developed at the JCVI to create cells and organelles with redesigned genomes to make microbes that can produce biofuels, pharmaceuticals, and industrially valuable molecules.

Prior to joining the JCVI, Dr. Glass spent five years in the Infectious Diseases Research Division of the pharmaceutical company Eli Lilly. There he directed a hepatitis C virology group and a microbial genomics group (1998-2003).

Dr. Glass earned his undergraduate (Biology) and graduate degrees (Genetics) from the University of North Carolina at Chapel Hill. His PhD work was on RNA virus genetics in the laboratory of Gail Wertz. He was on the faculty and did postdoctoral fellowships in the Microbiology Department of the University of Alabama at Birmingham in polio virology with Casey Morrow and mycoplasma pathogenesis with Gail Cassell (1990-1998). On sabbatical leave in Ellison Chen’s lab at Applied Biosystems, Inc. (1995-1997) he sequenced the genome of Ureaplasma parvum and began his study of mycoplasma genomics.

Risks of mirror bacteria

In this study we discuss the feasibility and potential risks of creating an alternative form of life called mirror bacteria.

Bringing cells to life … and to Minecraft: $30 million NSF grant to support whole-cell modeling at the Beckman Institute

Beckman researchers and collaborators received $30 million from the U.S. National Science Foundation to establish the NSF Science and Technology Center for Quantitative Cell Biology. The center will develop whole-cell models to transform our understanding of how cells function and share that knowledge with diverse communities through the popular computer game Minecraft.

Lessons from the Minimal Cell

“Despite reducing the sequence space of possible trajectories, we conclude that streamlining does not constrain fitness evolution and diversification of populations over time. Genome minimization may even create opportunities for evolutionary exploitation of essential genes, which are commonly observed to evolve more slowly.”

Even Synthetic Life Forms With a Tiny Genome Can Evolve
