Research Themes:

Understanding LIP gas emissions (e.g., CO2 and SO2 ) and developing geochemical proxies to quantify these emissions through the geological record, such as mercury and sulfur concentration and isotopic composition. 

Using paleoenvironmental proxy records such as carbon and oxygen isotope records from the geological past to investigate the environmental response to volcanism and other environmental change events. 

Understanding gas emissions and eruptive processes in modern (and LIP) volcanic systems and the environmental and climate effects of volcanic eruptions within the last few thousand years.
