Professor Shelley Arnott is a freshwater ecologist whose research spans fundamental to applied outcomes. She uses field and laboratory experiments, in combination with synoptic lake surveys and analyses of long-term data to understand environmental change in aquatic ecosystems. Much of her current focus is related to understanding the impact of road salt application, together with other environmental stressors including climate change, nutrient enrichment, and invasive species. She collaborates extensively with government, university, and NGO researchers and has led several international projects to assess variation in responses to environmental change across broad regions. She has trained 48 graduate students, 51 undergraduate thesis students, and mentored over 90 undergraduate summer students. Many of these students have continued in academia or environment-related jobs with government, NGOs, or consulting companies.
