Mary Jo Kirisits

Associate FacultyPh. D.,

Assistant Professor



Dr. Kirisits's teaching interests include biological treatment processes, biofilms, environmental microbiology, and molecular biology. Her research emphasizes the importance of applying the tools of molecular biology and microbiology to better understand and optimize the performance of biological treatment processes and to prevent their catastrophic failure. Currently, she has seven projects in her laboratory:

1. Microbial arsenic oxidation in drinking water
2. Microbial perchlorate and bromate reduction in drinking water
3. Hydrocarbon biodegradation in freshwater sediments of Onondaga Lake
4. Sulfur oxidation in biofilters: biomarker development
5. Development of intra-watershed model for the transport of bacteria in surface water runoff
6. Assessment of phenotypic variation in Pseudomonas aeruginosa biofilms
7 . Investigation of microbial community in pediatric ear infections
