RESEARCH INTERESTS:

 

My primary research interests are concentrated on the connection between microbial communities and environmental health focusing how these interactions can impact human health. Our anthropogenic footprint (e.g. industrial activities, pharmaceutical usage, introduction of invasive species, etc.) is changing soil and aquatic environments in ways that can impact human health. Bacterial and fungal communities are the first organisms to detect and adapt to anthropogenic activities, making them essential in detecting environmental degradation. The goal of my research program is determine how anthropogenic forces shape bacterial communities in terms of diversity and functional activity in different environments (e.g. soils, water, sediments, etc.), as these communities continue to carry out ecosystem processes and maintain diversity in the presence of anthropogenic disturbances. This research extends to the characterization of human pathogens (i.e. Clostridium perfringens) in the environment, basic physiological characterization of freshwater bacteria, and examination of microbial activities that associated with organic and inorganic contaminants (e.g. personal care products, flame retardants, nanoparticles).
