This research improves water and clinical diagnostics by replacing slow culture-based methods with rapid DNA-based detection. It enables faster, more accurate identification of pathogens, comprehensive microbial profiling, and tracing of contamination sources. By leveraging DNA amplification and sequencing, the work aims to deliver quicker, more reliable, and preventative public health solutions.

Quaternary ammonium compounds (QACs) are common disinfectants that enter waterways through household products. Researchers are studying their ecosystem effects using a whole-lake experiment in Canada’s Experimental Lakes Area. By examining microbial communities and other organisms, the project aims to determine how these persistent chemicals affect aquatic ecosystems and inform environmental regulation.
