Areas of interest

THE ECOTOX LAB
Ecotoxicology aims to quantify the effects of stressors on natural populations, communities, or ecosystems. Ecotoxicology is a broadly defined discipline and includes (but not limited to) the study of the movement of inorganic and organic contaminants through ecosystems, anthropogenic disruption of nutrient cycles, oceanic acidification as a consequence of climate change and the consequences of a changing community structure on geochemical processes.
