Interests & Expertise
Troy Skwor’s research focuses on antibiotic resistance within different bacterial populations, especially a group of bacteria known as aeromonads. These bacteria are found ubiquitously in nature, especially in freshwater ecosystems. However, they have been associated with a wide array of human diseases ranging from diarrhea to wound infections to severe forms of disease, like necrotizing fasciitis. Besides being ubiquitous in nature, the rapid acquisition of antibiotic resistance against a broad array of antibiotics can present a clinical challenge. Additionally, it can serve as a vehicle to transfer antibiotic resistant genes to other pathogenic bacteria. His studies utilize various molecular methods to detect antibiotic resistant mechanisms and their potential to be pathogenic to humans.
Another aspect of his research is studying alternative treatments against the bacterial populations with an emphasis on photodynamic therapy. This type of therapy uses a chemical, known as photosensitizers, in the presence of different wavelengths of light and oxygen, resulting in the production of reactive oxygen species capable of killing bacteria and cancer cells.
He has a strong interest in mentoring students and helping them develop thought processes to think empirically about the research projects, as well as life.
