My research focuses on extracting multi-millennium records of wildfires, mineral dust and trace metals atmospheric contamination within deep ice cores retrieved from polar and alpine glaciers. I use a multi-proxy approach to paleoenvironmental reconstructions employing a broad array of analytical techniques to characterize ice chemistry and determine the source of englacial impurities. The goal of the Ice Core geoChemistry and Climate Change (IC⁴) research program is to provide a spatial and temporal perspective on the current man-made alteration of the atmospheric composition and supply new scientific results with meaningful impacts for science, society, and decision-making. 

I am currently leading an NSF-CAREER project investigating how environmental changes have favored the transport of aerosols towards the High Arctic over the last millennium.
