UltraRes-rrn uses Nanopore sequencing and hierarchical rRNA operon profiling to achieve genomovar-level taxonomy resolution and microdiversity detection in microbial communities.

This paper introduces a field-deployable workflow for quantitative metagenomics using Nanopore sequencing and barcoded spike-in calibration, achieving species-level identification and absolute quantitation comparable to digital PCR.

The paper examines geographic structuring of Legionella and Mycobacterium populations across and within drinking water systems using 16S rRNA sequencing and flow cytometry.

This paper characterizes viral adsorption to Moore swabs using isotherm models, finding the Redlich-Peterson model best describes the relationship between viral concentration and swab uptake over time.

This study examines the decay and solid-liquid partitioning of mpox and vaccinia viruses in wastewater to improve wastewater-based epidemiology practices.

The paper curates nine genomic databases for fecal source tracking, summarizes their source-specificity, and tests their utility with mock water samples.
