Research interest
The effects of volcanic eruptions on the environment and the biogeochemical cycles of key elements such as carbon, iron, silicon and sulphur captivate me. My research involves field-based, experimental and modelling approaches to understand better the various factors and processes that dictate the short- and long-term reactivity and impacts of volcanic ash and gas emissions in the atmosphere, hydrosphere, biosphere and pedosphere. I am also interested in water-rock interactions in hydrothermally-active volcanic regions.
Keywords: Environmental effects of volcanic ash and gas emissions; Volcanic ash; Volcanic soils ; Fluoride ; Volcanic hydrothermal systems; Water-rock interaction
