Airborne Transmission of Influenza a Virus in Indoor Environments
… of the influenza virus in the environment during transmission between hosts. There is still controversy over the relative importance of various transmission routes, and the seasonality of influenza remains unexplained. This work focuses on developing new knowledge about influenza transmission via …

Advancing Biosecurity in the Age of AI: Integrating Novel Detection, Suppression, and Evaluation Approaches
… too late and lacking barriers against rapid airborne transmission. This thesis argues that robust biosecurity enables, rather than hinders, progress, and advances three key defensive capabilities. First, it evaluates blood metagenomics for pathogen-agnostic surveillance, reanalyzing public …

Engineering and targeting glycan receptor binding of influenza A virus hemagglutinin
… govern antigenic drift and efficiency of airborne transmission. This approach contributed to uncovering the relationship between receptor-binding affinity and efficiency of transmission of the 2009 H1N1 pandemic influenza A virus and also predicting the evolution of this virus into a more …

Toward a Mechanistic Understanding of Inactivation of Respiratory Viruses in the Environment
Airborne transmission of most respiratory viruses was not widely acknowledged until the COVID-19 pandemic. For viruses to transmit between infected and healthy individuals, they must remain stable (i.e., "survive") in aerosols and droplets. Their stability is influenced by many factors including …

Countermeasures Against Viral Hemorrhagic Fevers
… renal failure and even death. The route of transmission of VHFs depends on the agent. Some VHFs are spread by close contact with infected animals or humans, while others are spread by insects. The main reservoirs can range from rodents to arthropods. Some of the vectors include: the …

Presence and Stability of SARS-CoV-2 on Indoor Surfaces and Masks
… provide insight into the possibility of fomite transmission. Since most transmission occurs indoors where humans spent 90% of their time, we first focused on quantifying the contamination level of SARS-CoV-2, including both viral RNA and viable virus, on commonly touched surfaces and in the …

Droplet and Particle Dynamics in Aerosol Reactors and Environmental System
… my thesis focuses on understanding the spread of airborne pathogens like SARS CoV-2. A comprehensive model for respiratory emissions of droplets, droplet evaporation, and transport due to diffusion, gravitational settling, and ambient air flow, was developed. The considerations for viral load in …
