The metagenomics team focuses on analyses of microbes and microbial communities including metagenomics, metatranscriptomics, and integrations of other 'omics data. We collaborate on research directly with investigators in NIAID labs, as well as through the NIAID Microbiome Program. Some of these collaborations have led to the development of bioinformatic pipelines for public use - see the Related tools developed by BCBB (right panel) to learn about some of these tools.

We are available for research collaborations, short consultations to answer questions, one-on-one or group trainings, and pipeline development. See below for examples and selected publications.

Metagenomics Collaboration Areas

  • Amplicon metagenomics (16S, 18S, ITS, etc.)
  • Shotgun metagenomics including compositional and functional analyses of multi-kingdom mixed communities using short and long read data.
  • Community and diversity analyses.
  • Viral meta-transcriptomics.
  • Viral genome assembly and variant calling.
  • Comparative genomics.
  • Viral phylodynamics and molecular evolution.
  • Integration of other omics data with microbiome data.
  • Pathogen detection.
  • Development of custom pipelines and scripts for individual labs, including optimization for small and large-scale computation on microbiome datasets and databases in specific environments (HPC, containerization, cloud, etc.)
