Professor Marthe Monique Gagnon is a well established researcher in Ecotoxicology. She is the Leader of the Ecology Discipline, nested in the School of Molecular and Life Sciences at Curtin University.

Professor Gagnon has a remarkable career in Environmental Toxicology. She has led, and is currently leading, major research projects for industry, government and for the Australian Research Council.  Her excellent reputation has attracted her nominations as leader of long term, large scale research ventures such as investigation of oil spill impacts, and team leader of applied research programs in the north west of Australia. 

Research interests focus on the effects of industrial effluents on fish health, especially on the impacts of petroleum exploration and production on commercial fisheries. Other current research interests include chronic impacts of Oil Spills, pulp and paper effuents, endocrine disruption, and urban contamination. Contamination by specific chemicals are addressed (eg TBT), but also mixture of contaminants are investigated (eg endocrine disruptors, refineries’ effluents).
