Current research:

We are conducting metagenomics-based microbiome analysis and de novo genomic sequencing of algae and early-diverging land plants having established fossil records to:

  • infer the biogeochemical impacts of algae that have been ecologically prominent for hundreds of millions of years.
  • infer biogeochemical impacts of the first land plants.
  • better understand genetic, biochemical, structural, and reproductive transformations that occurred early in plant history.
  • design engineered systems that employ algae and early-diverging plants for new technological applications that include environmental remediation.
  • generate examples of bacterial, protist, and plant metagenomic and genomic systems for general biology and botany textbooks.
