Advancing Biosecurity for All

About our group

The Biosecurity and Bioforensics group is part of the Physical and Life Sciences Directorate at Lawrence Livermore National Laboratory. We focus on solving hard problems and developing new and innovative technologies.

Mission: Deliver intelligence-informed, science-based solutions to problems affecting human health and national security.

Vision: Combine cutting-edge sequencing technologies and bioinformatic approaches to develop data-driven models of infection and medical countermeasures.

Our current thrust areas are in:

  • Bioremediation
  • Metagenomic sequencing
  • Bioinformatic analysis of naturally-occurring communities
  • Advanced genetic engineering technologies such as CRISPR/Cas and how they affect cells and organisms

We work with various federal sponsors to deliver high-quality, science-based solutions to constantly-evolving needs.

Our capabilities

Our group’s core capabilities are:

  • High-throughput sequencing
  • Bioinformatics
  • Development of novel antimicrobials
  • Bioremediation
  • Advanced genetic engineering technologies

We work with various organizations across LLNL to support our sponsors by solving hard problems and developing new and innovative technologies.

We provide subject matter expertise for the intelligence community of potential dual-use technologies, and we partner closely with the Biological Science and Security Program in Global Security.
