Areas of Scholarly Expertise and Interest

Bacterial and fungal biofilms involved in infections, the natural environment, soil and sediment bioremediation and wastewater treatment


My research activities are focused on the microbiological topic of biofilms as they relate to either the external environment (bioremediation and clean-up of contaminated soil and sediments) or the human environment (infections and disease). Together with students, I have established a research program that focus on: a) Bioremediation of polychlorinated biphenyl (PCB) using biofilms in sediment and soil, where particular focus is concentrated on how biofilms can be used to enhance the microbiological activities of bacteria that perform bioremediation, thus improving the clean-up of contaminated areas making restoration of public areas to recreational activities possible; b) Multi-kingdom biofilm interactions between Staphylococcus epidermidis and Candida albicans using the nematode Caenorhabditis elegans as a model host, where focus is concentrated on how biofilms can cause chronic infections with many being non-responsive to antimicrobial therapy due to the biofilm mode of growth.

The research has been presented at regional, national and international conferences such as the annual American Society for Microbiology Maryland Branch Symposium, 10th International In Situ and On-Site Bioremediation Symposium, Euro-Biofilms, American Society for Microbiology Biofilm Meeting, Environmental Health 2013 and Interscience Conference on Antimicrobial agents and Chemotherapy (ICAAC). Research students are encouraged to present their research at meetings and several students have received awards for their presentations and have been awarded travel grants. In addition, the research results have been published in journals such as Biofouling, Microbial Ecology, Journal of Applied Microbiology, Journal of Industrial Microbiology and Biotechnology, Water Research, Water Science and Technology and Environmental Science and Technology.
