Interests and Expertise

My laboratory is interested in investigating virus-host interactions in eukaryotic and prokaryotic models. Past projects have focused on the vertebrate pathogens, Cottontail Rabbit Papillomavirus and Mouse Adenovirus. Both serve as model systems for human infections with Human Papillomaviruses and Human Adenoviruses. My work in the former model in the Kreider Lab at Pennsylvania State University led to a patent for monitoring papillomavirus replication in cell culture. Since 2017, my lab has changed focus to investigate the replication of bacterial viruses (bacteriophage) in cyanobacteria (blue-green algae). To be specific, we are investigating the infection of the cyanobacteria species Microcystis aeruginosa with the myovirus family, Ma-LMM01. Cyanobacteria of the genus Microcystis are responsible for toxin-producing nuisance blooms in freshwater lakes, including the Great Lakes. Using Ford Lake as our model system, we have detected the presence of this phage group and are assessing its impact on endogenous Microcystis strains in the lake. Understanding viral infection within these cells will help us understand the role of viruses in the regulation of algal blooms as well as the regulation of environmental nutrients.
