Research: “Predicting ecosystem disturbance status from stream invertebrate community structure”

I am an ecosystem ecologist who is interested in the intersection of humans and the environment, and what happens when the environment changes, whether due to natural cycles, climate change, or other anthropogenic disturbances.  My research focus has generally been on biogeochemical cycling and microbial ecology in soils and sediments.  I’m currently developing a project to use machine learning techniques with stream invertebrate community data to make predictions about whether stream ecosystems have been impacted by disturbance.  I am also developing and teaching workshops and online courses on beneficial skills for careers in environmental science, such as data analysis using R, and science communication and presentation.  This postdoctoral work is supported by the NSERC Collaborative Research and Training Experience (CREATE)-funded Watershed and Aquatics Training in Environmental Research (WATER) program at the Canadian Rivers Institute.

Research: “Effects of anti-sea lice pesticides used in salmon aquaculture on non-target organisms”

A variety of pesticides have been used in aquaculture to control infestations of sea lice, which are ecotoparasites of Atlantic salmon that can significantly affect fish health.  The pesticides are applied as a bath treatment to the fish and subsequently released into the surrounding environment, where native, non-target organisms could be exposed to these chemicals.

My research, in collaboration with Fisheries and Oceans Canada, involves laboratory testing to determine the effects of several anti-sea lice pesticides on native zooplankton and the effects of those pesticides that are pyrethroid-based and may accumulate in sediment on benthic organisms, including ecologically-sensitive amphipods and commercially-important polychaete worms.
