This research reconstructs viral transmission trees using genomic sequencing data to study how human behavior shapes infectious disease outbreaks. Analyzing COVID-19 transmission in Iceland revealed differences in infectiousness across quarantined and demographic groups, informing vaccine distribution strategies that improved population-level protection and influenced national public health policy.

This research examined how COVID-19 viral loads change over time across saliva, throat, and nasal samples. The study found that different sample types detect infection at different stages, demonstrating that testing method matters. These findings could improve diagnostic strategies for COVID-19, influenza, RSV, and future emerging respiratory viruses.

This research investigates how avian metapneumovirus spreads in poultry facilities and tests far-UVC light as a safe disinfection strategy. By studying viral survival on surfaces and in air, the work aims to prevent costly outbreaks, protect animal welfare, and reduce risks to human health through a One Health approach.
