My research investigates how freshwater soundscapes reflect ecological condition and respond to environmental and management-driven variation, using passive acoustic monitoring integrated with biological surveys and environmental measurements. I study freshwater systems across Ontario, including Lake Scugog and Canal Lake near Port Perry (examining how aquatic plant removal affects soundscapes), lakes, streams, and wetlands in Bruce Peninsula National Park (pairing hydrophone deployment with fish and macroinvertebrate sampling), and Canoe Lake in Algonquin Provincial Park (using acoustic telemetry to study burbot behaviour in relation to noise). Across these systems, my work examines how habitat type, water quality, and biological activity shape soundscape patterns, with implications for biodiversity assessment, ecological condition, and non-invasive freshwater monitoring.
Prior to my PhD project, I completed my Master鈥檚 at 91看片网 under the supervision of Dr. Stephanie Melles and Dr. Andrew Laursen. My study analyzed the trophic transfer of methylmercury and selenium between Chlorella pyrenoidosa and an aquatic annelid, Aeolosoma variegatum, to identify whether selenium exhibited a protective effect against mercury toxicity in these organisms across trophic levels.
