Research InterestsMy research focuses on microbial pathogenesis or how microbes cause disease. I have conducted studies of several different aspects on pathogenesis by bacteria. Currently the main focus of my lab is investigating how the bacterium Pseudomonas aeruginosa is able to secrete toxins via a Type III secretion system directly into cells of the host it is infecting. A Type III secretion system is used by many bacterial pathogens such as Salmonella to secrete toxins into cells of the host they are infecting. We are investigating why some toxins require an accessory protein called a chaperone for secretion to occur. My lab is also studying the regulation of the production of the exopolysaccharide alginate by P. aeruginosa. Production of alginate contributes to the ability of Pseudomonas to cause chronic lung infections in cystic fibrosis patients. We have been working to identify the factors that regulate alginate production and to characterize their role. I am also interested in developing new ways to treat infections and in testing the effectiveness of new antimicrobial drugs or chemicals.
